2 (30 p points) A follower rises through a total displacement of 6 inches with full rise cycloidal motion in 130 of cam rotation and then dwells at 6 inches for 90. Then the follower returns to the zero position with full fall cycloidal motion in 90 of cam rotation and finally dwells for S0 before repeating the cycle. The cam rotates at a angular velocity of 10 rpm cew and angular acceleration of 3 rad/sec2 cw. 2π o 5...

8.7 Draw the displacement schedule for a follower that rises through a total displacement of 3 in with cycloidal motion in 120° of cam rotation. The follower then dwells for 90° and returns to 0° with simple harmonic motion in 90° of cam rota- tion. The follower then dwells for 60° before repeating the cycle.
1. (40 points) A double-dwell cam is to move a follower from 0 to 2" in 120°, dwell for 80°, fall in 90 and dwell for the remainder. The total cycle is 5 seconds. Using cycloidal motion for t...
1. (40 points) A double-dwell cam is to move a follower from 0 to 2" in 120°, dwell for 80°, fall in 90 and dwell for the remainder. The total cycle is 5 seconds. Using cycloidal motion for the rise and 3-4-5 polynomial motion for the fall, find the follower displacement corresponding to the cam angle 0 at 90°, 180°, 230° and 320 respectively. Also find the maximum actual acceleration (in inch/sec2) during the entire motion cycle.

A flat-faced radial follower is driven through a total displacement of 38 mm. The follower moves upward 25 mm with constant acceleration for 120° and the remaining 13 mm with constant deceleration for 60° of cam rotation. The follower returns with simple harmonic motion in 90° and dwells for the remainder of the revolution of the cam. (a) For each type of motion, write an equation expressing S V AJ as a function cam angle 0 and draw S V...
