Practical use of the coefficient of friction calculations in module 7

Practical use of the coefficient of friction:

For 13 years I worked for a company that manufactured brake linings for cars and trucks.  The friction between a brake pad and a brake rotor is what stops a vehicle.  There were many engineers, mechanical, materials and chemical engineers, that worked in our lab developing different friction compounds for various vehicles.  We also had a testing facility where mechanics would put a set of experimental pads on a vehicle, then accelerate to 60 mph and slam on the brakes.  They would do this repeatedly while measuring stopping distances and the temperatures of the brake.
