The angular velocity of a wheel is `70 rad//sec` . If the radius of the wheel is 0.5 m , then linear velocity of the wheel is

A constant net torque equal to 20 N-m is exerted on a pivoted wheel for 8 sec, during which time the angular velocity of the wheel increases from zero to 100 re // min. The external torque is then removed and the wheel is brought to rest by friction in its bearings in 70 sec. Compute (a) the moment of inertia of the wheel about the rotation axis, (b) the friction torque(c)thetotal no. of revolutions made by the wheel in the70 sec time interval

A stunt rider on a unicycle is riding around thearena of a circus in a circle of radius R. The radius of the wheel of the unicycle is r and the angular velocity with which the wheel rotates is omega . What is the angular acceleration of the wheel ? (Ignore the fact that the wheel axis is inclined.)

Two wheels are connected by a belt.The radius of larger wheel is three times that of the smaller one.What is the ratio of the angular velocity of the two wheels i.e. (omega_(b))/(omega_(s)) ?

The figure shows a graph of the angular velocity of a rotating wheel as a function of time. Although not shown in the graph, the angular velocity continues to increase at the same rate until t = 8.0 s. What is the angular displacement of the wheel from 0 to 8.0 s?

The moment of inertia of a wheel is 1000 kg-m^(2) . At a given instant, its angular velocity is 10 rad//s . After the wheel rotates through an angle of 100 radians the wheel's angular velocity is 100 rad//s . Find the torque applied on wheel.

A wheel is rotating with an angular velocity of 3 rad s^(-1) . If the angular acceleration is 2 rad s^(-1) then calculate its angular velocity after 5 second.

If a poit on the circumference of a wheel having diameter 4 m has velocity of 1600 cm/s, then the angular velocity of the wheel will be

A wheel whose moment of inertia is 10kgm^(2) has an initial angular velocity of 20 rad//s . A constant torque of 20 Nm acts on the wheel. The time in which wheel is acceleration to 100 rad//s is
