Question

Chapter 2, Problem 2/182 The small sliders A and B are connected by the rigid slender rod. If the velocity of slider B is 2.73 m/s to the right and is constant over a certain interval of time, determine the speed of slider A when the system is in the position shown. R 55 2.28R UR B Answer: VA = m/s the tolerance is +/-2% Click if you would like to show Work for this question: Open Show Work LINK TO TEXT
