Design a cam to raise a valve with simple harmonic motion through 50 mm in 1/3 of a revolution,keep if fully raised through 1/12 revolution and to lower it with harmonic motion in 1/6 revolution.The valve remains closed during the rest of the revolution. The diameter of the roller is 20 mm andthe minimum radius of the cam is 25 mm. The diameter of the camshaft is 25 mm. The axis of thevalve rod passes through the axis of the camshaft. If the camshaft rotates at uniform speed of 100r.p.m. ; find the maximum velocity and acceleration of a valve during raising and lowering.

Draw the displacement diagram and profile of the cam operating a roller reciprocating follower and with the following data: Shaft diameter 10 mm; Minimum radius of cam 25mm; lift = 40mm; roller diameter=15mm. The cam lifts the follower for 120° with Simple Harmonic Motion (SHM) followed by a Dwell of 30° .Then follower lowers down during 150° of cam rotation with SHM followed by a Dwell period. If the cam rotates at a uniform speed of 100 RPM clockwise direction. Calculate the maximum velocity and acceleration during the ascent and descent period.

A cam have the following specifications: Follower to move outward through 5 cm during 90° of cam rotation, it dwells for the next 60°. The follower then return to its original position through an angle 0R and then dwell for the rest of the cam rotation of 110°. The displacement of the follower is to take place with constant speed motion during both the outward and return strokes. The least radius of the cam is 4 cm. If the cam rotates at 300 r.p.m., construct the displacement, velocity and acceleration diagrams. Also determine The displacement, velocity, acceleration and the pressure angle for the following angles (40°, 75°, 145°, 200°).

A cam, with a minimum radius of 30 mm, rotating clockwise at a uniform speed is to be designed to give a roller follower, at the end of a valve rod, motion described below : To raise the valve through 60 mm during 150° rotation of the cam;To keep the valve fully raised through next 30° (Dwell);To lower the valve during next 90°; and To keep the valve closed during rest of the revolution i.e. 90° (Dwell); The diameter of the roller is 20 mm and the diameter of the cam shaft is 30 mm. Draw the displacement, the velocity and the acceleration diagrams for one complete revolution of the cam when the cam shaft rotates at 180 r.p.m. Draw the cam profile when the line of the stroke is offset 20 mm from the axis of the cam shaft. The displacement of the valve, while being raised is to take place with simple harmonic motion and lowered with uniform acceleration.
