1. The problem statement, all variables and given/known data The ramp of a ship has a weight of 200lb and a center of gravity at G. Determine the cable force in CD needed to just start lifting the ramp, (i.e., so that the reaction at B becomes zero.) Also, determine the horizontal and vertical components of force at the hinge at A. 2. Relevant equations 3. The attempt at a solution I'm not even sure where to start.
