What is the role of a torsion spring?

• A. To compress energy and hold it
• B. To store mechanical energy by twisting
• C. To absorb shocks during movement
• D. To facilitate linear motion in machines

Answer: (B)

A torsion spring functions primarily by storing mechanical energy through twisting. When torque is applied to the ends of the spring, it undergoes a twist, which allows it to store energy in a manner similar to how a coiled spring stores energy through compression or extension. This stored energy can then be released when the torque is removed, and the spring returns to its original position. Torsion springs are often used in applications such as clothespins, watches, and various mechanical devices where rotational movement and energy storage are essential. The key characteristic of a torsion spring is that it operates based on the principles of angular displacement and can exert a restoring torque when twisted.
