The flywheel of a steam engine runs with a constantangular speed of 156 rev/min. When steam is shut off, the friction of the bearings and of the airbrings the wheel to rest in 2.20 h.
(a) What is the constant angular acceleration of the wheel, inrev/min2 ?
(b) How many rotations will the wheel make before coming torest?
(c) What is the tangential linear acceleration of a point 52.4 cmfrom the axis of rotation when the flywheel is turning at 72.5rev/min
(d) What is the magnitude of the total linear acceleration of thepoint in (c)?
