If the horizontal cable is moved so that it connects to the pole at a point 1/3L from the hinged bottom (but the cable is still horizontal and theta remains unchanged), will the magnitude of the torque exerted on the pole around the hinged bottom by the horizontal cable in the new position increase, decrease, or remain the same? i)The magnitude of the torque by the cable in the new position will increase. ii)The magnitude of the torque by the cable in the new position will decrease. iii)The magnitude of the torque by the cable in the new position will remain the same.

Solution

If the cable is moved to this new position the torque becomes:

T*1/3*L*sin 70

The previous torque was:

T*2/3*L*sin 70

SO TORQUE DECREASES

 If the horizontal cable is moved so that it connects to the pole at a point 1/3L from the hinged bottom (but the cable is still horizontal and theta remains un
