MAE 2600 (FS2014) Homework #18 (Section 16A-2) Name:_________________________ Due: Wednesday, 10/22/14 ID#: ( ) 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 пЃ± = 40п‚°, determine the barвЂ™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‚°.
