1. In the crank-connecting rod mechanism in the figure, the OA crankshaft passes through the O point. clockwise around the axis perpendicular to the plane, woA = 3000 rpm constant it freezes at angular speed. Connecting rod AB to the crankshaft at point A, and from point B It is articulated to the piston with the piston pin. For position e = 90: a) Determine the angular velocity of the connecting rod AB. WAB =? b) Determine the vectorial speed of point A of the crankshaft. VA =? c) Determine the vectorial speed of the B piston, Va =? d) Determine the vector velocity of the midpoint C of the connecting rod AB. And =? e) Determine the vectorial acceleration of point A of the crankshaft mm =? 300 mm 00m 1 0 = 90 WOA
