Question

The vertical bar AB has a mass of 150 kg with center of mass G midway between the ends. The bar is elevated from rest at θ = 0 by means of the parallel links of negligible mass, with a constant couple M = 5 kN∙m applied to the lower link at C. Determine the angular acceleration α of the links as a function of θ and find the force B in the link DB at the instant when θ = 30°.

The vertical bar AB has a mass of 150 kg with center of mass G midway between the ends. The
bar is elevated from rest at 0 = 0 by means of the parallel links of negligible mass, with a
constant couple M = 5 kN·m applied to the lower link at C. Determine the angular
acceleration a of the links as a function of 0 and find the force B in the link DB at the instant
when 0 = 30°.
