Transcript of How a Seat Belt is Made

Think about the design
When your making a seat belt you have to think about is this going to hold back any mass or will it be 100% reliable with the smallest of passengers to the largest. Also will it engage from the smallest of force to the largest of forces. Which is part of Newton's second law of motion. It needs to be easy to operate and you have to have the resources to manufacture the seat belt. If i was making a seat belt i would make one like the harnesses used on roller coasters. If you think about it it holds you in tight when you going really fast and turning quick on roller coaster so why wouldn't it hold you in a car? It holds you back from you going forward when the brakes are applied fastly which is part of Newton's 1st law because what in motion stays in motion.
Manufacturing the seat belt.
When you are manufacturing your seat belt you need to make sure you can make it the same way all the time and that it stays durable. You also need to make sure that its standardized. You need the materials to make it over and over again.
Test it
How Seat Belts are Made
With Newton laws
Newton's first law of motion
Second law
Acceleration is produced when a force acts on a mass. The greater the mass (of the object being accelerated) the greater the amount of force needed (to accelerate the object).
Third law
For every action there is an equal and opposite re-action
An object at rest will remain at rest unless acted on by an unbalanced force. An object in motion continues in motion with the same speed and in the same direction unless acted upon by an unbalanced force
this is also called the law of inertia.
When you test the seat belt you are testing Newton's 2nd and 3rd law. You need to make sure that no amount of mass will let it brake and that when there is any force on it that it will hold you back. It needs to be able to hold back any kinds of body sizes and force. It also needs to be easy enough for any age group to put on from children to elders. You also need to make sure that when you do the double harness that both sides work not just one.
So after all the seat belt is a pretty awesome and useful invention don't you think? It definitely helps keeps you safe in the car but only if you have it on. It also has a lot to do with Newton's laws of motion.
