The rotating desk, shown in drawing below, is a simplification of a mechanical component in a rotary machine. The mass of the solid desk is 15 kg and the mass of material scraped from a single hollowed-out hole is 150 grams. Determine the required horsepower to rotate this desk at 2500 rpm using an angular acceleration of 50 rad./s (1 rpm- 2n/60 rad./s and 1 horsepower 745.7 Watt) 1-I cm tholar)
