Tire manufacturers recommend that you check your tire pressure monthly to avoid unnecessary tire wear and enhance safety. This is best done when the tires are cold meaning; the car has not been driven for at least 2 hours. Since you leave for work before the sun comes up you decide to inflate your tires to the recommended pressure right after you get home from work in the afternoon when the tires are still warm. What would you find if you rechecked your tire pressure after the tires have cooled down?
A.Tire pressure has decreased because there is a decrease in kinetic energy of themolecules resulting in more collisions with the inside walls of the tire thusincreasing the pressure inside the tire.
B.Tire pressure has increased because there is a decrease in kinetic energy of the molecules resulting in fewer collisions with the inside walls of the tire thus decreasing the pressure inside the tire.
C.Tire pressure has increased because there is an increase in kinetic energy of the…

A datum when used in manufacturing is primarily used for?
Define the functional relationship to another feature on a part, or they have a functional relationship in an assembly. They are the origin from which many Geometric tolerances are measured.
Datums are used to describe how one part must fit or align to a mating part.
A datum should be placed on the smallest surface of the part to be sure that the mating part would fit.
Datums assure that parts will always fit together.

Tyre dynamics
Describe the methods of obtaining the forces generated by the tyre.
Laboratory methods: "Flat Trac" test platform and Drum test platform.
Field methods.
If possible, cite scientific papers.

Part 2
Set up a spreadsheet solution to this problem. This will require that you derive one
formula to express the relationship between the friction coefficient, the spring constant,
and the spring compression; and a second formula to find the cost of using different slide
and spring types. Set up your spreadsheet as shown below. You can fill in the
"Acceptable?" column manually, rather than using a formula. Turn in a copy of your
spreadsheet/Matlab work

For my assigment, I was asked to design a electric motorbike that has a peformance equal to Honda CBR1000 Fireblade which has a petrol engine. A part of the the assignment is to calculate " An estimate of maximum Power your new motor will need to generate to match the Honda’s performance." I can make the assumption, apart from changing the motor, everything else is going to stay the same so the fairing,the rider and etc they're gonna be the same for the two bikes. So can you please tell me how I can calculate that which information would I need ?
