Question: the x and ymotions of guides a and b with...

Question details

The x- and y-motions of guides A and B with right-angle slots control the curvilinear motion of the connecting pin P, which slides in both slots. For a short interval, the motions are governed by x 20 o.71t2 and y 29 0.353, where x and y are in millimeters and t is in seconds. Calculate the magnitudes of the velocity v and acceleration a of the pin for t 2.8 s. Sketch the direction of the path and indicate its curvature for this instant. Answers: mm/s mm/s
