The cable from drum A turns the double wheel $B,$ which rolls on its hubs without slipping.

Determine the angular velocity $$ and angular acceleration $$ of drum $C$ for the instant when the

angular velocity and angular acceleration of A are $3\mathrm{.}9ra\frac{d}{s}$ and $3\mathrm{.}5ra\frac{d}{s^2}$ respectively, both in the

counterclockwise direction. The angular velocity and acceleration of $C$ are positive if

counterclockwise, negative if clockwise.

Answers:

$=$

i

$ra\frac{d}{s}$

$=$

$ra\frac{d}{s^2}$
