Question

the ______________ is an applied tensile load that the fastener must support without permanent deformation.
clamp load
proof load
yield point
ultimate tensile strength

Explanation:

The proof load is the applied tensile load a fastener can support without permanent deformation. Clamp load is related to pre - tightening force, yield point is the stress at which plastic deformation starts, and ultimate tensile strength is the maximum stress a material can withstand while being stretched.

Answer:

B. Proof Load
