Q1. Why is tension considered a force rather than a weight or movement, and what role does
it play in mechanical systems?
Ans: Tension is a force because it represents the pulling force transmitted along a string,
cable, or rope when it is taut. Unlike weight, which is a force due to gravity acting on
mass, or movement, which is a change in position, tension specifically refers to the force
exerted along a flexible connector. In mechanical systems, tension is crucial for
transmitting forces between components, such as in pulleys or cables, enabling the
transfer of loads and motion. Understanding tension helps in analyzing stresses and
ensuring the integrity of structures and machines under load.
