A cam drives a flat reciprocating follower in the following manner. During the first 90° rotation of the cam, the follower moves outward through a distance of 30 mm with SHM. The follower dwells during next 90° cam rotation. During the next 90° cam rotation, the follower moves inward with SHM. The follower then dwells next 90° cam rotation. Draw the cam profile and calculate the maximum values of velocity and acceleration when cam rotates at 10 rad/s.
A cam drive is used for a mechanism incorporated in a shoe-sewing machine. The cam follower must rise outward 0.5 in. with cycloidal motion in 0.7 s, dwell for 0.2 s, fall 0.25 in. with cycloidal motion in 0.5 s, dwell for 0.2 s, fall 0.25 in. with cycloidal motion in 0.5 s and then repeat the sequence. Determine the required speed of the cam and graphically plot a follower displacement diagram.

If the period of acceleration of the follower is 60° of the retardation during the lift, determine the main dimensions of the cam, the acceleration at main points. What is the maximum acceleration and deceleration during the lift?
A cam is used to operate a platform that repeatedly lifts boxes for a height of 40 mm as shown. One cycle of the cam has the following motion requirements: Rise to 40 mm in 1.5 s, Dwell for 0.25 s, Fall for 20 mm in 1 s; Dwell for 0.25 s; Fall a further 20 mm in 1s and the cycle repeats after this. The required speed of cam is rpm and the angle turned by cam during the Rise motion is degrees. *Write your answer only as numbers, DO NOT add any text 40 mm
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°).

(iii) Dwell for 1.5 s. (iv) Repeat the sequence. Using the motion equations, find the follower acceleration at t = 0.5 s for the cycloidal motion and angular displacement of cam for the return motion.

The reciprocating radial roller follower of a cam is to rise 3 cm with a Simple Harmonic Motion (SHM) in 120°, dwell for 60°, then return with a cycloid motion to its starting point in 120°, and finally dwell for the remaining 60°. If the prime-circle radius is 3 cm, draw the displacement diagram, and then the cam profile for clockwise cam rotation (if the roller-circle radius is 0.5 cm).

Project 4: Cam-follower is used in a range of applications to convert rotational motion to linear motion of a follower at specific characteristics and time period. Your role is to construct the profile of a cam that specify the following motion requirements of a follower: Motion.1: first part of lift period at constant acceleration of 2 m/s? over rotation of 30° Motion.2: second part of lift period at constant deceleration of 2 m/s? over the next 30° Motion.3: follower produces constant displacement for next 90° Motion 1 and 2 are the rise/lift period and must be 15 mm displacement and the fall is identical to rise/lift period and must return to the base again at 210°.
