Meriam, Kraige & Bolton — Plane Kinematics of Rigid Bodies: Problem 5_77

5/77 The bar of Prob. 5/66 is repeated here. By the method of this article, determine the velocity of end A. Both ends remain in contact with their respective support surfaces. [From Prob. 5/66: The ends of the 0.4-m slender bar remain in contact with their respective support surfaces. If end B has a velocity \( v_B = 0.5 \text{ m/s} \) in the direction shown, determine the angular velocity of the bar and the velocity of end A. The diagram shows the bar making a \( 30^\circ \) angle with a vertical wall, and the angle between the wall and the inclined floor is \( 105^\circ \).]
