10 examples of tensionforce in 8 class
Answers
Answer:
Tension is a force working along the length of a medium, especially this force is carried by a flexible medium, like a rope or cable. The flexible cords which carry muscle forces to other parts of the body are known as tendons.
Any flexible connector like a string, rope, chain, wire, or cable, can exert pulls only parallel to its length. Therefore, a force carried by a flexible connector is a tension with a direction parallel to the connector.
It is important to understand that tension is a pull in the connector. The tension force pulls outward along the two ends of the string. This Tension in the rope must equal to the weight of the supported mass, which can be easily proved using Newton’s second law. Here, the only external forces acting on the mass will be its weight W and the tension T supplied by the rope. Thus,
Net force =

where T and w are the magnitudes of the tension and weight and their signs indicate a direction, with up being positive here. Thus, just as we may expect, the tension equals the weight of the supported mass.
