Which of the following is true for an object in dynamic equilibrium?

The object is moving at a constant velocity.

The sum of the moments is non-zero.

The forces are unbalanced.

The object is at rest.

What is the condition for a system to be in static equilibrium?

The sum of forces in both horizontal and vertical directions must be zero.

The sum of the forces and moments must be non-zero.

The sum of forces must be positive.

The sum of the masses must be zero.

The moment of a force is defined as:

The distance between the point of application of the force and the pivot.

The weight of the object.

The force applied to a point.

The turning effect of a force.

The concept of equilibrium in a system can be described as:

A state of motion only.

A state of balance where forces and moments are balanced.

A state where forces are unbalanced.

A state of rest only.

In a simple experiment with a beam, when weights are placed at different positions, what determines the direction of rotation?

The distance from the pivot point.

The mass of the weights.

The position of the beam.

The force applied.
