a) 3) (30P) A disk cam is to be designed with reciprocating cylindrical follower such that the follower rises 1-16 mm during the first 240 of cam motion, then returns during the next 120 of cam motion. Using Simple Hormonic Motion (SHAO for both rise and return; a) Construct the cam displacement profile for 360 of cam rotation. b) Evaluate the first and second order kinematic coefficients for both rise and return stroke c) Calculate the maximum velocity and acceleration of the rise and return stroke if the cam rotates at 800 rpm in clockwise direction Full-rise SHM motion Full-return SHM motion y' (1- COS y= (1+ cos B no Frie = (1-cos (119) 8-80s (38-14) I fall = 1/6 (1+ cos(-1)) = 8+8 cos (106)
