Consider the portion of an excavator shown. At the instant under consideration, the hydraulic cylinder is extending at a rate of 5 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. Answers: V = ( a = ( i i 2.7' O 36° 2.0' A er + i er + i B eg) in./sec eg) in./sec²
