Cam's profile generation with rotation roller follower

Move the Point P on the displacement diagram and observe how the cam's profile is generated

- The line that links points O and P is the line that moves the roller follower. It is the fixed line to the ground and in it there is the relative movement of the follower with respect to the ground. -Change the cam's base circle radius with the slider and observe that when the Base circle radius r0 is small, the deffect is visible in the right of the applet, the profile generated ends in a vertex.
