Automotive Understanding Gear Ratios: Inputs vs Reality
The gear ratio is the ratio of angular displacement, angular velocity, angular acceleration, torque etc of the input with respect to output. However, I would like to know that which of these variables will be scaled exactly to the gear ratio in reality, as there might be some friction in the...- 961008

How does quenching affect the fracture energy of a material?
Is it true that quenching will decrease the toughness of material and tempering the quenched material will then increase the toughness? I need an explanation in term of the effect of quenching and tempering on the structure of the material.- 961008

High School Friction Calculation: Formula for Determining Wheel-Surface Friction
The friction I refer to is the friction per revolution of the wheel. The "big" refers to the diameter of the wheels, with the same width. -

High School Friction Calculation: Formula for Determining Wheel-Surface Friction
How can we calculate the friction between the wheels and the surface in contact? I know that big wheels will have a greater friction, but what is the formula to calculate it?
