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 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 development of compressive stresses…

A round bar specimen is subjected to a tensile test. After fracture, it is observed that the diameter at the fractured section remains approximately the same as the original diameter. What material was the round bar most likely made of?

A) Mild steelB) Cast ironC) AluminumD) Copper Explanation: As per IS 1608, when a ductile material like mild steel is subjected to tensile test, it undergoes significant plastic deformation before failure. This causes necking at the fractured section, where the diameter reduces substantially. However, brittle materials like cast iron and aluminum do not undergo plastic…
