Assume the angle of the upper bar (link 2) is input. For this system, find the acceleration of translation of the box, angular accelerations of the footplate (3) and ace;eratopm components for point P on the foot plate. Use the data for the cases given in the table below. Solve for the unknown variables in the model for the cases presented below. 1 2 3 3 2 dot 2 3 dot 3 r1 r2 r3 r4 r3b r4_dot APx APx
