Question
A crate sits on a platform supported by links AB and CD. The combined mass of the crate and the platform is 20 kg and point G is their center of mass. The links have negligible mass. At the instant shown torque M is being applied to link AB to give the links angular velocity ? = 4 rad/s counterclockwise and angular acceleration ? = 12 rad/s^2 counterclockwise. Find the torque M needed. Find the reaction force on the platform at B. Find the force in link CD.
The answers are 60 N-m of torque counterclockwise. The answer for the reaction at B is 120 N to the left and 108.35 N up. The answer given for the force in link CD is 72.15 N in tension. Thanks in advance!
