2) The vertical bar AB has a mass of 100+abkg with center of mass G midway between the ends. The bar is elevated from rest at =0 by means of the parallel links of negligible mass, with a constant couple M=5+bkNm applied to the lower link at C. Determine the angular acceleration of the links as a function of and find the force B in the link DB at the instant =(30+a). (ab is the las two digits of Student ID. For example if Student ID is 2000114526 then a=2b=6 and ab=26. Hence Mass =126kg and M=11 kNm,=32 )
