Plot the displacement diagram for a cam with circular follower of diameter 30 mm and it has offset of 15 mm. the required motion is as follows; 1- Rising 40 mm in 100 with Cycloidal motion 2- Dwell 100 3- Falling 30 mm in 100 with Uniform acceleration motion 4- Falling 10 mm in 60 with Uniform velocity Then draw the cam profile to give this displacement diagram if the minimum circle diameter of the cam is 30mm.
