A follower rises 4 in in
180\deg
of cam rotation and then returns during the next
180\deg
of cam rotation. The cam rotates at 60 rev/min. For the given follower motions, determine: (a) mathematical expressions for the displacement, velocity, acceleration, and jerk of the follower; (b) the magnitudes and locations of maximum velocity and maximum acceleration of the follower; (c) the follower displacement, velocity, acceleration, and jerk when the cam angle is
120\deg
; and (d) the follower displacement, velocity, acceleration, and jerk when the follower displacement is 3 in during the rise segment of the motion.
5.26 Uniform motion.
5.27 Modified uniform motion (with constant velocity from
45\deg
to
135\deg
and from
225\deg
to
315\deg
).
5.28 Simple harmonic motion.
Please solve the 5.28
