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_forward
- Turbine blades used in Jet engines can be made from materials such as nickel-based superalloys. Principle as such, ceramic materials such as zirconia or other alloys based on steel can even be used. In some cases, with a thermal barrier coating of blades to minimize exposure of Blade material to high temperatures it may also need to be coated. When selecting a material for the turbine blade and successfully in a turbine engine what design parameters do you consider for the coating that will work? Different parts of the engine are different please note that it is exposed to temperatures and not all blades are exposed to relatively high operating temperatures.
