Question

When the slider-crank mechanism is at the position shown, link AB has an angular velocity ofMAB=3.2 rad/s, and an angular acceleration of aAB=0.8 rad/s. Assume that links AB and BC aremassless and that slider C weighs 12 lbs. The system parameters are as follows: LAB=2.5 ft, LBC=1.8ft, B=45°, 0=45°. Note that link BC is in horizontal position.
