The load $L$ is lowered by the two pulleys which are fastened together and rotate as a single unit. For

the instant represented, drum A has a counterclockwise angular velocity of $5\mathrm{.}1ra\frac{d}{sec},$ which is

decreasing by $3\mathrm{.}4$ rad $\frac{?}{sec}$ each second. Simultaneously, drum $B$ has a clockwise angular velocity of

$3\mathrm{.}3ra\frac{d}{sec},$ which is increasing by $5\mathrm{.}5ra\frac{d}{sec}$ each second. Calculate the accelerations of points $C$

and $D$ and the load $L.$
