Dec 28, 2020 · Tension is a contact force transmitted through a rope or similar object when forces pull on the object's opposite ends. For example, gravity pulls the rope holding a tree-branch swing downwards; the resulting tension between the branch and gravity pulls the swing upwards and the branch downwards.

How do you find the force of tension?
In physics, tension is the pulling or stretching force transmitted axially along an object such as a string, rope, chain, rod, truss member, or other object, so as to stretch or pull apart the object. In terms of force, it is the opposite of compression.
What is the tension in the rope? First we draw a force diagram of all the forces acting on the box. Now we use Newton's second law. The tension is directed both vertically and horizontally, so it's a little unclear which direction to choose.

- Do you have to account for the mass of the rope, too?Yes but until you get to the point where you able to use calculus on these problems the wire/rope is considered to be massless.

Jan 13, 2024 · A tension is a force along the length of a medium; in particular, it is a pulling force that acts along a stretched flexible connector, such as a rope or cable. The word “tension” comes from a Latin word meaning “to stretch.”
Tension refers to the force that is transmitted through a string, rope, wire, or other similar object when it is pulled tight, trying to restore the object to its original, unstretched length.

The tension on an object is equal to the product of the mass of the object and gravitational force added to the product of the mass and acceleration. Mathematically, it is represented as follows: T = mg + ma
