To pull a car out of a ditch, one end of the rope POR is tied around a pillar at P and the other end is tied to the car at R. A force of 100N is applied to the Center O of the rope and perpendicular to PR. find the tensions in the rope if the angle POR = 150 degrees

1 answer

By symmetry, force/2 =Tension*sin75

Tension=50/sin75
