Q1:- The circular arc cam rotates uniformly at 600 rpm and operates aflat-footed reciprocating follower. The base circle radius= 24 mm,the nose circle radius= 3 mm, the center distance between thebase and nose circles = 30 mm and the distance between the pitchcircle center to the center of curvature of the circular flank= 120mm. The follower retaining spring is to be designed so that at thebeginning of the nose, the spring force is 10% greater than thevalue required to hold the follower on the cam, and in the full liftposition, the spring force is 5% greater than the required value.Find the spring stiffness and the spring force at the zero liftposition if the total mass o the reciprocating parts is 1.25 kg.

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°).
