H18-1. The bar is confined to move along the vertical and inclined planes. If the velocity of the
roller at A is vA = 2.8 ft/s when  = 40, determine the bar’s angular velocity and the velocity of
roller B at this instant. Neglect the size of the rollers.
H18-2. Peg B mounted on hydraulic cylinder BD slides freely along the slot in link AC. If the
hydraulic cylinder extends at a constant rate of vB = 0.4 m/s, determine the angular velocity and
angular acceleration of the link at the instant пЃ± = 35п‚°.
