Horizontal oscillation of the spring-loaded plunger E is controlled by varying the air pressure in the horizontal pneumatic cylinder F, as shown in figure QB2a. The plunger E has a velocity of 3 m/s to the right when ?=30?, determine graphically the position of C; the center of instantaneous zero velocity for the bar ABD.
AB= 70mm
BD= 140mm
Calculate the distances AC, BC and DC.
(c) Knowing the vA is perpendicular to CA, determine the velocity vA and the angular velocity of the bar ABD.
(d) Determine the downward velocity vD of the roller D in the vertical guide.
