1.) A lawnmower engine claims to provide 18 hp of power and 6.25 ft lb of torque. If this is true, what must be the rotational speed in RPM?

2.) The conversion of the shaft power of a wind turbine to electricity is the function of the generator. Assume it has an efficiency of 0.45. If the wind turns the shaft of a generator at 26.2 rad/s (about 250 RPM) and the generator produces 300 W of electricity, what torque is produced by the wind on the shaft?
