Problem: 5
The AB link on a piston mechanism rotates at a constant angular velocity of 3 rad/s. What is the angular velocity of the bar BC at the instant when link AB makes a 30? angle with the horizontal? (cw = clockwise)a. 1.12 rad/s (ccw) b. 0.941 rad/s (ccw) c. 1.34 rad/s (cw) d. 1.53 rad/s (cw) e. 1.78 rad/s (cw) The AB link on a piston mechanism rotates at a constant angular velocity of 3 rad/s.
