Instantaneous Center of Zero and Known Velocities - Example Problem 4.4-6

The rectangular plate is confined by rollers within slots at A and B.  When θ = 20^o, point B is moving at v_B = 10 m/s.  Determine the velocity of points C and D at this instant.  The dimensions of the plate are a = 100 mm and b = 50 mm.

Given:

• θ = 20^o
• v_B = 10 m/s
• a = 0.1 m
• b = 0.05 m

Find: v_C, v_D

Draw the velocity direction for point A and then locate the IC for the plate. Click on the image when done.
