A) Toughness
B) Proof Resilience
C) Ductility
D) Malleability

According to IS 800:2007, Clause 2, Proof resilience is defined as the maximum strain energy that a material can absorb per unit volume without any permanent deformation. This is an important design consideration as it indicates the ability of a material/component to absorb shock and impact loads by undergoing elastic deformation. Table 2 of IS 800:2007 provides the resilience values for structural steel.

The correct option is B) Resilience

If a part is constrained to move and heated, it will develop:

A) Tensile stressB) Compressive stressC) Shear stressD) No stress Table of Contents Explanation: Explanation: As per theory of thermal stresses, when a body is restricted from free expansion or contraction, it develops internal stresses when subjected to change in temperature. If a constrained part is heated, it tends to expand. But restriction to movement causes…
