Concept explainers

Torsion

In mechanical engineering, torque, torsion, and twisting moment are three of the most important concepts which have different meanings. Torque is the consequence of a moment of a force that produces an angular acceleration in a body or induces rotational kinetic energy in a body. For instance, in an automobile, the power transmission shaft is a body that is always under rotation due to the external torque acting on it, this torque is created by the engine.

La Figure: Compression spring The squared type of compression spring has total 8 coils shown in the figure. The spring is made of music wire with wire diameter and mean diameter of 0.30 inch and 3.0 inch respectively. Initially the free length of the compression spring was proposed as 3.75 inch. Is this safe to compress the spring to the solid length (L.) considering the factor of safety 1.5? If it is safe why it is safe? Show your calculation. If this is not safe, propose the maximum free length of this spring.
