Single Dwell Mechanism with slider

This is a Single Dwell mechanism with a slider. Point C remains stopped while point P is going through a nearly circular piece of its path

-Move the point A and observe that point P (red point) describes a trajectory nearly that a circumference -L2=L3=L4 -The point O is the center of the circumference -While point P (red) translates along the piece of the curve that is almost an arc of circunference, point C remains stopped in the center of the circunference, and therefore, the piston (in the slider) remains stopped -Move point D to change the orientation of the slider
