When switched on, the grinding machine accelerates from rest to its operating speed of 2940 rev/min in 5 seconds. When switched off, it coasts to rest in 36 seconds. Determine the number of revolutions turned during both the startup and shutdown periods. Also determine the number of revolutions turned during the first half of each period. Assume uniform angular acceleration in both cases.

The prescribed motion for an application is as follows: (i) Rise 60 mm in 2.5 s using the constant velocity motion scheme. (ii) Return in 3.0 s using the cycloidal motion scheme. (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.
