Answer 2

Option  b) It is closed coiled spring

The helix angle is very small about 2⁰. The spring is open coiled spring.

• The plane containing each coil is virtually at right angles when the helix angle is minimal, which is why it is known as a closed coiled spring.
• Closed Coiled Helical Springs: Also referred to as tension/extension springs, these springs are made to withstand stretching and twisting. The ends of these springs have an eye or a hook for attachment. High torsion or bending load won't damage these springs.
• In essence, closed coil springs are extension springs designed to experience axial elongation in response to tensile loading. In contrast, a sufficient spacing is maintained between two adjacent coils in an open coil helical spring.
