my wright brothers infographic

Extra information on the Wright Brothers:

The wright brothers were ingenious inventors, they invented what we now know today as the aeroplane.

 

BornOrville: August 19, 1871

 

Wilbur: April 16, 1867,

 

Overille the younger of the two brothers was born in 1871 and he died in 1948, Wilbur the older of the two brothers was born in 1867 and died in 1912.

 

In 1884 the whole family moved to dayton. This was because Overille and Wilbur’s father was a Bishop. Dayton, Ohio was the center of the Brethen Church.

 

At about the same time their mother grew ill with typhoid and Wilbur just out of high school put off collage to nurse his mother. Their mother died in 1889 the same year that Overille dropped out of high school to open a printing shop.

 

In 1890 Wilbur joined Overille as part of the printing shop.

 

In 1894 Wilbur and Overille got swept up into the bicycle craze and they began repairing bicycles. This soon became a full time job and in 1896 they began manufacturing their own bicycles.

 

“In 1896, the same year the newspapers were filled with accounts of flying machines. Wilbur and Orville noticed that all these primitive aircraft lacked suitable controls. They began to wonder how a pilot might balance an aircraft in the air, just as a cyclist balances his bicycle on the road. In 1899, Wilbur devised a simple system that twisted or “warped” the wings of a biplane, causing it to roll right or left. They tested this system in a kite, then a series of gliders.”

 

“They made their first test flights at Kitty Hawk, North Carolina, on the shores of the Atlantic where the strong winds helped to launch the gliders and the soft sands helped to cushion the fall when they crashed. Their first two gliders, flown in 1900 and 1901, failed to perform as the Wrights had hoped. The gliders did not provide enough lift nor were they fully controllable. So during the winter of 1901-1902 Wilbur and Orville built a wind tunnel and conducted experiments to determine the best wing shape for an airplane. This enabled them to build a glider with sufficient lift, and concentrate on the problem of control. Toward the end of the 1902 flying season, their third glider became the first fully controllable aircraft, with roll, pitch, and yaw controls.”

 

“During the winter of 1902-1903, with the help of their mechanic, Charlie Taylor, the Wrights designed and built a gasoline engine light enough and powerful enough to propel an airplane. They also designed the first true airplane propellers and built a new, powered aircraft. Back in Kitty Hawk, they suddenly found themselves in a race. Samuel P. Langley, Secretary of the Smithsonian Institution, had also built a powered aircraft, patterned after a small, unmanned “aerodrome” he had flown successfully in 1896. To add to their frustrations, the Wrights were delayed by problems with their propeller shafts and the weather, giving Langley time to test his aircraft twice in late 1903. Both attempts failed miserably, however, and Langley left the field to the Wrights. On December 17, 1903, Wilbur and Orville Wright made the first sustained, controlled flights in a powered aircraft.”

 

 

They continuously improved their gliders and eventually what was a glider became an aeroplane.

 

As their fame grew orders for air-crafts poured in.

 

Then in 1912 Wilbur tired and stressed out from from all the work got typhoid and died.

 

Overille’s last project was fittingly re-building the 1905 flyer III. In 1948 Overille after fixing a door bell at his home in dayton he suffered form a heart attack and died a few days later. therefore he unfortunately did not get to see the unveiling of the machine.

 

 

Scientific application:

My prediction is that the less steep the slope is the less effort force is needed to pull the hole punch up the inclined plane.

 

This is a video journal of our experiments on inclined planes:

 

 

My pictures of our experiment:

 

Screen Shot 2013-10-08 at 7.41.40 AM

This is the first inclined plane that we measured. It was a steep inclined plane and the force that we used to pull the hole punch up it was 4n.

Screen Shot 2013-10-08 at 7.42.35 AM

This is the second inclined plane that we measured. It was steep but not as steep as our first one. The effort-force we used to pull the hole punch up the inclined plane was 3.5n.

Screen Shot 2013-10-08 at 7.43.39 AM

This is the third slope that we measured and it was a moderately steep slope. The effort force we used to pull the hole punch up the slope was 3.5n also.

 

Screen Shot 2013-10-08 at 7.44.09 AM

 

This is the fourth slope that we measured, it was a gentle slope and the effort slope that we used to pull the whole punch up it was 3n.

 

 

Screen Shot 2013-10-08 at 7.44.40 AM

This was our fifth and final slope that we measured, it was a very gentle slope. The effort force we used to pull the hole punch up it was 2n.

Screen Shot 2013-10-09 at 9.11.46 AM

Between “B and C” is what we call the run. Between “A and B” is what we call the rise. To find out the gradient of the slope we then divide rise by the run.


Screen Shot 2013-10-09 at 9.12.09 AM

When there is a steeper slope the effort force is going to be more because it is then harder to pull the item up the slope because it is steeper.

My conclusion is that my prediction was correct as in that when the slope becomes steeper the force-effort need to pull an object up it, becomes more and when the slope becomes less steep the force-effort needed to pull that item up the slope will become less.

 

Innovative process:

Screen Shot 2013-10-07 at 2.42.09 PM

 

There will be a fixed frame as part of my machine. The top part will be a lever. There will be a fixed rod with a blade on the end of it. The fulcrum / pivot will be where the lever connects to the main frame so it can swivel. The load is the blade on the end of the fixed rod. There will be a cylinder covering most of the egg which will be made of an insulated material. So when you hold the egg you won’t burn your fingers. The top part of the egg will be sticking put still so you can cut it off. The eggcup holder on the frame will be connected to the main frame. The eggcup will then slide into the holder ready for the egg. Nothing will fall off (EG. The egg) my machine because you will wither be holding it or it will be connected to the frame in some way. See design above.

 

Comparing my two designs:

My first design does meet the specification points because all the specification points make sense and are relevant to this machine. This machine corresponds to the specification points in such a way that I will be able to fulfil them and it will work. Both of my machines will eventually meet the same need of the person who wants to cut off the top off their egg without burning their fingers.

 

My second design doesn’t meet all the specification points but it meets most of them the only real ones that it doesn’t meet are: the size and the colour. This would be ok because the colour doesn’t really matter and the size doesn’t make a huge difference to the machine either.

 

Specification points: The specifications either of my machines will / won’t meet:

Target Market: People who like soft boiled eggs. Design 1 = (1) Design 2 = (1)

Function of Machine: To cut the top off a hot soft boiled egg without burning your fingers. Design 1 = (1) design 2 = (1)

 

Materials Required: 

Wood. Design 1= (1) design 2 = (1)

A lever/linkage. Design 1 = (1) design 2 = (1)

A metal blade. Design 1 =(1) design 2 = (1)

Plastic to make the cradle. Design 1 = (1) design 2 = (0)

Dimensions: Egg hole: 12 centimeters= circumference of an egg.  Design 1 = (1) Design 2 = (0)

 

Positioning of lever: The lever is going to be positioned on the same side as the blade (the rear) and then also connected with a nut and bolt to the blade. Design 1 = (1) design 2 = (1)

 

Size of handle: The handle is going to be 2 centimeters long. design 1 =(1)

Design 2 = (1)

Size of blade: The blade is going to be 15 centimetres long. design 1 = (1) Design 2 =(1)

 

Size of cradle:  The cradle is going to be 4 centimeters long to hold the egg. Design 1 = (1) design 2 = (0)

 

Maximum weight of finished machine: The maximum weight of my machine is going to be no more than 1kg. design 1 =(1) design 2 = (1)

 

Colour: The machine that I am making is not going to be painted, the wood will be varnished with non toxic varnish. Design 1=(1) design 2 = (0)

 

The life span of my product:  will be three years long because it will be a sturdy well built and Structured machine. Design 1 = (1) design 2 = (1)

 

The cost to make the machine:  7 euros. Design 1 = (1) design 2 = (1)

 

Health and safety:

When varnishing the machine you would have to be careful In which varnish you would buy because some varnish is toxic and when the egg is being cut some varnish could get on it and harm the consumer so when varnishing the machine make sure it is non toxic varnish. Deisgn 1=(1) design 2 = (1)

 

WARNING: There is a blade on the machine parents please keep away from young children.

Design 1 = 22/22

Design 2 = 12/22

The questions I will ask my client:

1a. From looking at the drawing of my machines

 

b. How can I improve my machines?

You can improve your machine by reducing the amount of little things that are a bit impractical and can fall off and get lost easily.

 

c. Which machine do you think is most practical?

The first machine because it has a proper holder for the egg which the egg cant fall out of because the hole for it to sit in is a limited size and it has a cradle for it.

 

d. How much would you be prepared to pay for either of my machines?

I would be prepared to pay a maximum of 15 euros.

 

e. Which machine do you think would be easiest to store?

The machine I think would be easiest store would be the first machine because with the second machine there would be more little things that could fall off and get lost in the cupboard.

 

f. Which machine do you think would be more eye catching/appealing to the eye?

I think the second machine would be more eye catching/appealing to the eye because of all the little parts could be painted different colours.

 

g. Which machine do you think is safer for younger children to be around?

I don’t think either of the machines would be safe for children to be around because there is a big sharp blade on both machines and that could be dangerous.

 

h. What name do you think I should give to my machines? The eggatine/ The egg decapitator?

I think the egg decapitator is a better name.

 

2. Which one would you buy?

I would buy the first machine that you made.

 

2a.Which machine would you like me to make for you?

I would like you to make the first machine please.

 

This is the interview with my client :

These are my final drawings of my machine.

The machine I will be using is the first one:

Evaluating my specification points:

Target Market: People who like soft boiled eggs.This machine is specifically for people who like boiled eggs because if you don’t like boiled eggs wont use this machine because they wont make boiled egg and there for wont need to cut off the top of them.

 

Function of Machine: To cut the top off a hot soft boiled egg without burning your fingers.  This specification point will apply to my machine because that’s what my machine is made to do.

 

Materials Required:

 

Wood.

 

A lever/linkage

 

A metal blade

 

Plastic to make the cradle

 

All of these materials will be required to make my machine. So this specification point will apply to my machine.

 

Dimensions: Main body:

 

Height: 15 centimetres. The height of my machine will be 15cm, which is equal to 30mm

 

Width: 12 centimetre. The width of my machine will be 12cm, which is equal to 24mm          

 

Depth: 1 centimetre. The depth of my machine will be 1cm, which is equal to 2mm.

 

Dimensions: Stand:

 

Height: 3 centimeters. The stand will be 3cm in height, which is equal to 6mm

 

Width: 16 centimeters. The stand will be 16cm in width, which is equal to 32mm

 

Depth: 2 centimeters. The depth of the stand will be 2cm, which is equal to 4mm

 

Dimensions: Egg hole: 12 centimeters= circumference of an egg

 

 

Positioning of lever: The lever is going to be positioned on the same side as the blade (the rear) and then also connected with a nut and bolt to the blade. The blade will be positioned in this way because it is needed on this side to allow the blade to drop with it and for it to then successfully cut off the top of the egg.

 

 

Size of handle: The handle is going to be 2 centimeters long. This specification point wont be met because there will now not be a handle you will use your hand to push down the lever with the blade on the end of it.

 

 

Size of blade: The blade is going to be 15 centimeters long. The blade will not be 15 centimeters long anymore the blade will now be 14mm long because if it was 15 cm long it would be the same length as the whole main part of the machine.

 

Size of cradle:  The cradle is going to be 4 centimeters long to hold the egg. The cradle is going to be 4 cm long, which is equal to 8 mm long. so this point will apply to my machine.

Maximum weight of finished machine: The maximum weight of my machine is going to be no more than 1kg. My machine will not be more than 1 kg because if it is it will be very heavy and less practical and harder to move/transport. So this point will apply to my machine.

 

Colour: The machine that I am making is not going to be painted. The wood I will be varnished with non toxic varnish. My machine will be varnished because this will then make sure that the machine will not give you splinters while you use because the wood will have been filed and finished. So this point will apply to my product.

 

The life span of my product:  will be three years long because it will be a sturdy well built and Structured machine. This is true to my product because it will be a made of good, sturdy materials.

 

The cost to make the machine:  7 euros. The machine should be no more expensive than this for me to make it or it is going to be harder for me to sell it to supermarkets ECT. because then they wont buy it because it will then be harder for them to sell it and also make a profit. So this point will apply.

 

Health and safety:

When varnishing the machine you would have to be careful In which varnish you would buy because some varnish is toxic and when the egg is being cut some varnish could get on it and harm the consumer so when varnishing the machine make sure it is non toxic varnish. If I use toxic varnish when building this machine I will harm my consumers and they will sue me so this point will apply.

WARNING: There is a blade on the machine parents please keep away from young children. This specification point will apply to my machine because for young children it will be dangerous for them to be operating this machine because of the big blade on it.

 

 My plan: The full sized product:

1. Making sure that all of my materials can be found in the DT lab because if they can’t I will have to go out and buy them
