Texts: Given any rigid body in equilibrium, the sum of ALL moments about ANY point is zero. Hence, the sum of all moments about node A must be zero in order for the tailgate to be in equilibrium. What is the magnitude of the force in each cable (F)? Note: the force in the diagram below is shown as 2F because there is a cable on each side. Assume that each cable shares the load equally and find the force in just one cable. The given forces are the total of all gravity loads acting on the tailgate. Provide your answer in lb, but don't include units in your submittal.
