Question 5

A light loading platform is hinged to a building and held horizontal by an upward support force. Initially, a crate is 0.70 m from the hinge and the support force is applied 1.40 m from the hinge. The crate is moved 0.20 m farther from the hinge. The point where the support force is applied is moved 0.30 m farther from the hinge. The weight of the crate does not change. What is the ratio of the original support force to the new support force?
