The system shown lies in the vertical plane. The trolley A is moving to the right with a constant acceleration aA. Attached to the trolley is a rope AB of negligible mass. Attached to the end of the rope is a thin uniform bar BC of length L and mass m. When the trolley A is accelerating at constant aA, the angles θ and ϕ are both constant. Determine these two constant angles in this steady state as functions of one or more of the given quantities (i.e., L, m, and aA). Note that .
