Homework Answers
a)
V = r w = 0.45* 10^-2* 60* 2* 3.14 = 1.6956 m/s
======
b)
angular velocity of wheel
w' r' = r w
w' * 2* 10^-2 = 1.6956 = 84.78 rad/s
angular velocity of roller shaft
wr = 60* 2* 3.14 = 376.8 rad/s
=====
Comment before rate in case any doubt, will reply for sure.. goodluck

In the ligure, wheel A of radius A-8.74 cm is coupled by belt 8 to wheel of radius - 20.4 cm. The angular speed of wheel A is increased from rest at a constant rate of 2.18 rad/s. Find the time needed for wheel to reach an angular speed of 131 rev/min, assuming the belt does not slip. (Hint: If the belt does not so, the linear speeds at the two rims must be equal Number Units the tolerance is...

An electric motor turns a llywheel through a drive belt that joins a pulley on the motor and a pulley that is rigidly attached to the flywheel as shown in the figure below. The flywheel is a solid disk with a mass of 53.0 kg and a radius R -0.625 m. It turns on a frictionless axle. Its pulley has much smaller mass and a radius of 0.230 m. The tersion in the upper (taut) segment of the belt is...

Consider the following two situations involving two rotating objects that are joined together somehow (a) In rewind mode, many cassette and video recorders have one spool that turns at constant angular velocity pulling the tape from the other spool. What happens to the angular velocity of the other spool as the tape moves from one spool to the other (changing the outer radii of the spools). Why? Would this work in play mode? (b) A wheel (call it wheel A)...

In the figure, two 5.60 kg blocks are connected by a massless string over a pulley of radius 2.20 cm and rotational inertia 7.40 times 10^-4 kg-m^2. The string does not slip on the pulley; it is not known whether there is friction between the table and the sliding block; the pulley's axis is frictionless. When this system is released from rest, the pulley turns through 1.00 rad in 179 ms and the acceleration of the blocks is constant. What...
