Determine the torque applied to the shaft of a car that transmits 450 hp and rotates at a rate of 3000 rpm. Please explain, thank you!
Formula as W(shaft)=2*(pi)*n*T

The higher the astm grain-size number, the coarser the grain is. a)-true b)-false

Awall of 0.5m thickness is to be constructed from a material which has average thermal conductivity of 1.4 w/mk. the wall is to be insulated with a material having an average thermal conductivity of 0.35 w/mk so that heat loss per square meter shall not exceed 1450 w. assume inner wall surface temperature of 1200°c and outer surface temperature of the insulation to be 15°c. calculate the thickness of insulation required.
