Consider the portion of an excavator shown. At the instant under consideration, the hydraulic cylinder is extending at a rate of 9 in./sec, which is decreasing at the rate of 3 in./sec every second. Simultaneously, the cylinder is rotating about a horizontal axis through O at a constant rate of 15 deg/sec. Determine the velocity v and acceleration a of the clevis attachment at B. Determine the r and 8-components of velocity and acceleration. B 2.5' 3.6' A 37° Answers: V, = i in./sec Ve = in./sec in./sec? ag = in./sec? a, = i i
