- 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.arrow_forwardA 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.arrow_forwardA 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, dwellfor 0.2 s, fall 0.25 in. with cycloidal motion in 0.5 s, dwell for 0.2 s, fall 0.25 in. withcycloidal motion in 0.5 s and then repeat the sequence.
