Question

Q 52 A shaft rotates against a turning force
exerted by a 20 kg block attached to the
drum circumferentially and hanging by
an inextensible string at 300 rpm. If the
drum dimension is 200 mm (dia), shaft is
of diameter 30 mm and piston force is a
simple cosine function, the engine rating
capable of accomplishing this would be:
Ops: A
315 W. 2.1cos(15.7t) kN.​
