For mechanical shown below, assume that link 2 angular velocity is 50 rad/sec CW and link 2 angular acceleration is 1600 rad/sec CW. Determine VB, VC, VE, W3, W4, , , , 3, 04. Velocity scale: Acceleration scale: 1 cm: 10 in/sec 1 cm: 500 in/sec E AB= 1.75" AD = 3.55" CD = 2.75" BC = 5.15" BE=2.5" EC=4.0" Using loop closure method, solve the instantaneous acceleration of the slider P (in the diagonal slot) and the velocity of point Q when the distance between Op and P is 6 inches and all other information is as shown on figure, the crank link Op to A is increasing in speed 10 rad/sec and is currently rotating at 100 rad/sec. AGA Rigid www 35 Op 2 2 According to linkage shown in the figure, Link 3 must be perpendicular to link 2. If the angular velocity of link 2 is 100 rad/sec CW and p = 60, Using loop closure method, calculate the acceleration of point C and the angular acceleration of link 3. BA 10" Graphically, draw the entire acceleration polygon and use it to find both the magnitude and direction of a and ace at the instant shown. Also, find magnitude and direction of a, 3 and 4 when a) The crank angular velocity @ is constant at 100 rad/sec CCW. b) The crank angular velocity w3 is 100 rad/sec CCW and accelerating at 25000 rad/sec Velocity scale: 1 cm: 20 in/sec Acceleration scale: 1 cm: 4000 in/sec 2 in = 45 0C = 4 in O,D= 6 in 0,0,= 6 in 0 2 in 6 in E
