A 100 kg timber pole AB is at rest when is zero. The pole is connected to a cable at point A. An electric motor installed on a stationary frame lifts up the pole as shown in the figure below by exerting a constant torque of 75 N.m. Find the angular velocity of the pole when 0 is 60°. Highlight both the value and direction clearly. What is the tension in the cable when 0 is 75⁰? Note: The friction and masses of the pulley and the cable can be neglected. The diameter of the disk motor that the cable is attached to is 20 cm. l I Electric Motor (M) Cable T = 75 N.m C
