Which of the following is an example of a body undergoing translationa...
An object is said to be in equilibrium when there is no external net force acting on it. When an object is in equilibrium, it does not accelerate. If it had a velocity, the velocity remains constant; if it was at rest, it remains at rest.
If all the forces acting on a particular object add up to zero and have no resultant force, then it’s in translational equilibrium. Examples would be a book resting on a bookshelf, or someone walking at a steady, constant speed.
An object that’s not rotating or doing so at a steady speed, the sum of the torques acting on it equaling zero, is at rotational equilibrium. Some examples of this are a Ferris wheel turning at a constant velocity, two children of equal weight balanced on either side of a seesaw, or the Earth rotating on its axis at a steady speed.

Example of a Body Undergoing Translational Equilibrium

Body at Rest on a Table

A body undergoing translational equilibrium is a body in which the net force acting on it is zero, and it is either at rest or moving with a constant velocity in a straight line. One example of such a body is a body at rest on a table. Let's break down the explanation into the following headings:

Definition of Translational Equilibrium

Translational equilibrium is a state in which a body is at rest or moving with a constant velocity in a straight line. It occurs when the net force acting on a body is zero.

Factors Affecting Translational Equilibrium

There are two factors that affect translational equilibrium:

- Net force acting on the body
- Frictional forces acting on the body

In order for a body to be in translational equilibrium, the net force acting on it must be zero. If there is a net force acting on the body, it will either accelerate or decelerate. Additionally, frictional forces must be taken into account. If there is friction between the body and the surface it is resting on, the force of friction will act to oppose any motion of the body.

Body at Rest on a Table

A body at rest on a table is an example of a body undergoing translational equilibrium. The net force acting on the body is zero, and the force of gravity acting downwards is balanced by the normal force of the table acting upwards. Since the body is at rest, it is not accelerating.

Conclusion

In conclusion, a body undergoing translational equilibrium is a body in which the net force acting on it is zero, and it is either at rest or moving with a constant velocity in a straight line. A body at rest on a table is an example of such a body, as the net force acting on it is zero, and it is not accelerating.
