Posted on A) ToughnessB) Proof ResilienceC) DuctilityD) 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…

Posted on A) 0B) 0.25C) 0.5D) 1 According to IS 456:2000, Clause 6.2, Poisson’s ratio is defined as the ratio of transverse strain to axial strain. For a material that does not change in volume under stress, the transverse and axial strains must be equal in magnitude but opposite in sign. Therefore, the Poisson’s ratio for such…

Posted on Masonry walls have been used in construction for centuries owing to their durability, fire-resistance, and aesthetic appeal. Masonry is the building of structures using individual units bonded together with mortar. Masonry walls are constructed by laying masonry units like bricks, concrete blocks, stones, etc. in horizontal layers along with mortar that binds them together. The…

Posted on Concrete is one of the most widely used construction materials in the world. Its popularity stems from its high compressive strength, durability, and versatility. However, concrete is a complex composite material whose properties depend on its composition and structure. One of the most important properties of concrete is its modulus of elasticity. This post will…

Posted on 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…

Posted on 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…
