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 $=(30+a{)}^o.($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 $M=11$

$kNm,=32)$ STUDENT ID:$21049034$
