Conservation of Energy

In physics, the rule of the conservation of energy states that energy doesn’t disappear from the atmosphere; instead, it changes its form from one type to another. Energy is one of the most important physical quantities in nature, and it cannot be created or destroyed — only transformed.

Question

The sliders A and B are connected by a light rigid bar of length /= 22 in. and move with negligible friction in the slots, both of which lie in
a horizontal plane. For the position where xA = 18 in., the velocity of A is va = 3.O ft/sec to the right. Determine the acceleration of each
slider and the force in the bar at this instant. The acceleration of A is positive if to the right. The acceleration of B is positive if up (as
viewed in the diagram). The force in the rod is positive if in tension. Remember that the motion takes place in a horizontal plane, so the
force of gravity is not a factor.

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 = 12 +0.55t² and y= 16-0.57t3, 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 = 2.5 s. Sketch the direction of the path and indicate its curvature for this instant. B P A| x
