The system shown lies in the vertical plane. The trolley A is moving to the right Wa constant acceleration a4. Attached to the trolley by a pin is a thin

uniform bar 1of mass m and length L. Attached to the end of the bar AB by a pin is a thin uniform bar BC of mass m and length L. When the trolley A is accelerating at constant a A-angles 0 and ø 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 a4). Note that cos(4 - x) = sin x.
