This mechanism can be viewed in action following this link: https://youtu.be/E-tCzfbt6cs

If the crank has a clockwise angular velocity and angular acceleration of w = 0.2rad/s a=.17rad/s^2 find the acceleration of point B in the center of the slider constrained to move on the circular path as shown. Note that I have dimensioned this model with the horizontal and vertical distances between pin points, this the slider acting just like a link pinned at the point shown. The crank is vertical. Use these distances directly in your computation rather than finding angles.
