The crane shown in the figure is lifting a 363-kg crate
upward with an acceleration of 3.03 m/s2. The
cable from the crate passes over a solid cylindrical pulley at the
top of the boom. The pulley has a mass of 155 kg. The
cable is then wound onto a hollow cylindrical drum that is mounted
on the deck of the crane. The mass of the drum is 187 kg,
and its radius (the same as that of the pulley)
is 0.693 m. The engine applies a counterclockwise torque
to the drum in order to wind up the cable. What is the magnitude of
this torque? Ignore the mass of the cable.
