Question

the load, usually expressed in terms of torque, at which the fastener fails by being twisted off about its axis is called ______________. torsional strength tensile strength shear strength fatigue strength

Explanation:

Torsional strength is the ability of a material or component to resist twisting. When a fastener fails by being twisted off about its axis under a load (expressed as torque), this load - torque value represents its torsional strength. Tensile strength is related to stretching forces, shear strength to forces that cause one part of a material to slide over another, and fatigue strength to repeated loading.

Answer:

Torsional Strength
