Question
In writing your solution to this exercise be sure to show all of your work in an organized manner. This means starting with a known equation, showing all your calculations on a separate line and writing your final answer with units. A 1600 kg car moving at 70 mph applies its brakes to come to rest. The action of the brakes converts 65% of the car's initial kinetic energy into heat generated in the steel brake pads. The pads have a mass of 18kg. Determine the resulting stress that occurs in the brake pads as a result of linear expansion. If an answer cannot be determined then briefly explain why.
Explanation / Answer
Stress is given as
Stress = Force /Area
since we have not been given the area of the pad, we can not calculate the stress acting on the pad
