- Suppose you're selecting materials for a frictional braking system which will be used to bring a moving body to a stop. It is imperative that you choose a braking surface material which will not thermally degrade as mechanical kinetic energy is converted to thermal energy during the braking process. You have a list of candidate materials for your braking system which includes maximum permissible average power dissipation. In order to relate average power dissipation rate to your system's mechanical properties (and select an appropriate material), what information will you need? mass of the body your braking system is decelerating maximum speed of your body at the time the braking system is applied duration of the braking process O all of the abovearrow_forwardDefine “material” in engineering sense.
