Question

Q3:
The motion of
of an oscillating flywheel is defined by the relation
Ꮎ
cos 4nt, where 0 is expressed in radians and t in seconds. Knowing
that . = 0.5 rad, determine the angular coordinate, the angular velocity, and the
angular acceleration of the flywheel when (a) 1 = 0, (b) t= 0.125 s.
