Can anyone help me with these questions? Thanks:

1) What conditions must be present for (a)translational equilibrium and (b)rotational equilibrium of a rigid body?

2) If these conditions for equilibrium are satisfied, is the rigid body necessarily in static equilibrium? Explain.

3)Why are clockwise and counterclockwise referred to as "senses," rather than directions?

Im sure this stuff must be present in your course material.

1) What conditions must be present for

(a)translational equilibrium :

The net force on the body is zero, hence its velocity is constant, not
necessarily zero


(b)rotational equilibrium of a rigid body?

The net torque on the body is zero, hence its angular velocity is
constant, not necessarily zero



2) If these conditions for equilibrium are satisfied, is the rigid body necessarily in static equilibrium? Explain.

No. Static equilibrium refers to the condition when the velocity linear
or angular as applicable is zero.


3)Why are clockwise and counterclockwise referred to as "senses," rather than directions?

The tangential velocity of different points on the same body which is spinning can point in all directions. Diametrically opposite points in fact will point in opposite directions; so which direction can one specify?

However when the words clockwise / counter clockwise are used we can sense what they mean
