If the end 'B' of the rod is moving upward along the wall at the speed of 3.3 m/s find angular velocity of the cylinder assuming that it is rolling without slipping.

Considering rod AB

$WAB= VB/IB \\ = 3.3/1.3 \cos30 \\ = 2.93 rad/s$

Now, $VA = WAB . IA \\ = 2.93 * 1.3 \sin 30 = 1.905 m/s$

Now, As cylinder C is rolling without slipping, its ICR lies at point of contact between cylinder and ground

$WC = VA * 0.6 = 1.905 * 0.6 = 1.143 rad/s$

Angular velocity of cylinder is 1.143 rad/s
