Consider the portion of an excavator shown. At the instant under consideration, the hydraulic cylinder is extending at a rate o in./sec, which is decreasing at the rate of 3 in./sec every second. Simultaneously, the cylinder is rotating about a horizontal axi through O at a constant rate of 12 deg/sec. Determine the velocity v and acceleration a of the clevis attachment at B.
