Why is tension the same on both sides of a rope?

Explanation: The rope experiences the same pulling force on both sides, and therefore it is in a state of static equilibrium (i.e. it is at rest consequently has a net force of zero). Newton’s third law states that every force occurs as a member of an action/reaction pair of forces.

Why is the tension force the same?

Since the rope is light, that means the net force on each piece of the rope has to be very small. That means the change in the tension must be very small. Usually the rope is so light compared to the blocks that we can neglect the change in tension along it entirely, so the tension is the same at every point.

Why is the tension the same throughout the massless string?

Since there is no mass in the string so no force can be applied on it from one side since F=m*a and m is zero. So when v apply a force F from BOTH Sides of the string the tension in the string remains constant and that is equal to F.

Can tension in same string be different?

No. To understand this consider a mass less string whose one end is fixed with rigid and fixed object and at the other end a tension T is applied.

Is tension always equal on both sides of a pulley?

Pulley: A pulley serves to change the direction of a tension force, and may also (in the case of multiple-pulley systems) change its magnitude. The tension of an “ideal cord” that runs through an “ideal pulley” is the same on both sides of the pulley (and at all points along the cord).

Why the tension in a string must be uniform?

The tension of the string is uniform in some cases: If String is mass-less and its particles don’t move with respect to each other (i.e. string is inextensible or if it is extensible, it reach to its final tension). If String is mass-less and there is no friction between string and pulley.

What is the tension in the string?

Tension in the string. The tension is defined as: “The force exerted by a string when it is subjected to pull”. If a person is holding a block of weight W attached to the end of a string, a force is experienced by him .

Can a String have two tensions?

There should only be one tension in a massless string. Let a massless rope hang from a ceiling and two monkeys of different weights are holding on to the rope at two different heights.
