?explanations needed, thanks.
A wheel of radius a, with its mass concentrated on the rim, is rolling with velocity v round a circle of radius (R >> a), maintaining a constant inclination alpha to the vertical. Show that v = a omega = R Ohm, where omega is the angular velocity of the wheel about its axis, and Ohm (<< Omega) is the precessional angular velocity of the axis. Use the momentum equation to find the horizontal and vertical components...

A wheel of radius a, with its mass M concentrated on the rim, is rolling with velocity v round a circle of radius R(>> a), maintaining a constant inclination alpha to the vertical. If omega is the angular velocity of the wheel about its axis, and Omega (Omega<< omega) is the precessional angular velocity of the axis, what is it's total angular momentum vector? (Using spherical polars and taking the centre of mass of the wheel as origin.)

The angular velocity W of a rotating solid body is a vector whose magnitude is the rate angular displacement (radians per second) and whose direction is that in which aright-handedscrew would advance if turned in the same direction. The position vector r of a point is the vector from the origin of coordinates to the point. Show that the velocity of any point in rotating solid body v=[W×r], relative to an origin located on the axis of rotation.
When we consider a moving body in mechanical equilibrium, which of the following must be true?...
When we consider a moving body in mechanical equilibrium, which of the following must be true? (There may be more than one answer.) The object's linear speed is a constant. If the object is rotating, it must be rotating about an external, fixed point. The object's direction is not changing. If the object is rotating, its rotational speed must be constant.
