The crank CB oscillates about C through alimited are causing
     The crank CB oscillates about C through alimited are, causing crank OA to oscillate about O. For the instant shown, the angular velocity of CB is 2 rad/s counterclockwise. At this instant:  Velocity of the pin B is  0.1 5 i m/s;  0.3 j m/s;  -0.15j m/s;  - 0.3 m/s;  zero.  Angular velocity of the link AB (omega_AB) is  1.234 rad/s counterclockwise;  0.857 rad/s clockwise;  0.857 rad/s counter clockwise;  0.342 rad/s clockwise;  none of these.  Velocity of the pin A is  0.0429i m/s;  0.0324j m/s;  0.324i m/s;  - 0.0429i m/s;  none of these.  Angular velocity of the link OA (Omega_OA) is  0.428 rad/s counter clockwise;  0.134 rad/s clockwise;  0.428 rad/s clockwise;  insufficient data;  none of these.  The x and y coordinates of the instantaneous center of the link AB with respect to the hinge point O are  (175, 100) mm;  (0, 100) mm;  (0, 50) mm;  (175, 50) mm;  none of these 
  
  Solution
1. V=*r=2*0.075=0.15m/s and will be negative as counterclockwise (C) -0.15j m/s
2. (C) 0.867rad/s counterclockwise
3.
4.
5. (B) (0,100)mm
