A rotator platform supports a large uniform cylindrical solid of 5346 kg, radius = 0.75 m and length = 2.5 m. Electric motors exert a 40 Nm
torque about the axis A-A. What is the time required to move the cylinder from its stow-a-way position (0 = 0 degrees) to its deployed
position (0 = 90 degrees)? Take the moment of inertia I to be (1/3)ML². For the first 45 degrees of rotation, motor torque is applied. During the
next 45 degrees of rotation, the torque is reversed in order to bring the cylinder to rest at the deployed position. (PUHQ121)
a) 033.46 seconds
b) 041.83 seconds
c) O20.91 seconds
d) O11.15 seconds
