The vertical bar AB has a mass of 100+ab 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+b kNm 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 0 = (30+ a). (ab is the las two digits of Student ID. For example if Student ID is 2000114526 then a=2 b-6 and ab-26. Hence Mass= 126 kg and M=11 kNm, 0 = 32) B 1.5 m C 1.5 m M O C A 0.6 m 1.8 m Answer:
