(2 Points)

Tensile stress

Compressive stress

Bending stress

Torsional shear stress​

Answer 1

Answer:

torsional shear stress

Answer 2

When the helical extension spring is subjected to axial tensile force, the type of stress induced in the spring wire is torsional shear stress (option 4th).

• Torsional stress, also known as shear stress, is created by the body twisting.
• The helical extension spring is formed of wire that has been twisted into a helix shape.
• This twisting or torsional stress is due to the force applied to the body of an object along its longitudinal axis.
• Tensile stress causes an object's length to rise, compressive stress causes an object's length to shrink, and bending stress causes an object's flexibility to prevent it from deforming.
• As a result, the spring wire is under torsional stress due to twisting.
