Question

Define helical springs and close coiled helical springs

Answer 1

Closed Coiled Helical Springs: Designed to resist stretching and twisting, these springs are also known as tension/extension springs. These springs can endure stress caused by high torsion or bending. The coils are closely wound to each other, and lie on the same axis of the helix.
