    A 1000 lb uniform platform is rotated by a green shaft (centered) as shown. The ends of the green shaft are each connected to a motor - one on either side of the platform. If the platform starts out from rest in horizontal position, how much torque is need to rotate this platform 180 degrees in 3 seconds (assume gravity is present)?

    A 1000 lb uniform platform is rotated by a green shaft (centered) as shown. The ends of the green shaft are each connected to a motor - one on either side of the platform. If the platform starts out from rest in horizontal position, how much torque is need to rotate this platform 180 degrees in 3 seconds (assume gravity is present)?

    Solution:

    Some new features were added on the figure.
    If the platform starts from rest and assuming that a constant torque is applied, then an ...

    Solution Summary

    The problem shows how to compute the needed torque to be applied to a platform which is required to rotate 180 degrees in 3 seconds. The expert examines a uniform platform rotated on a green shaft.
