Which forces needed for the rotational motion about a fixed axis?

How many degrees of freedom does a rotational motion about fixed axis?

Derive the equation of angular momentum in the case of rotational motion about a fixed axis.

Which component of torque is responsible for the rotation motion about Z-axis?

Why the angular momentum perpendicular to the axis (L_(_|_)) in a rotational motion about a fixed axis?

The rotation of earth about its axis is………..

A ring of radius R and linear charge density lambda on its surface is performing rotational motion about an axis perpendicular to its plane. lf the angular velocity of the ring is omega , how much current is constituted by the ring?

How to be verify fixed axis?

What does torque measured in rotational motion?

The fastest possible of rotation of a planet is that for which the gravitational force on material at the equtor barely provides the centripetal force needed for the rotation. Show then that the corresponding shortest period of rotation is given by T=sqrt((3pi)/(Grho)) where rho is the density of the planet, assumed to be homogeneous. Evalute the rotation period assuming a density of 3.0 gm//cm^(2) , typical of many planets, satellites, and asteroids. No such object is found to be spinning with a period shorter than found by this analysis.

Write the formula of work done by torque in rotational rigid body about a the fixed axis.
