For the inverted slider-crank linkage in the posture illustrated, the angular velocity of the crank is ω2 = 24 rad/s cw. Make a complete velocity analysis of the linkage. What is the absolute velocity of point B? What is its apparent velocity to an observer moving with link 4? Locate all instant centers for the mechanism and use it to calculate VB.
