Q1:

With increasing carbon percent in steel beyond 0.8%, its ultimate tensile strength (UTS) and __________ is not affected.

A impact strength

B percent elongation

C hardness

D both 'b' & 'c'

ANS:A - impact strength

Impact strength refers to the ability of a material to withstand sudden, high-stress loading without fracturing. It measures the energy absorbed by a material during impact loading, typically expressed in joules or foot-pounds. Impact strength is essential for materials used in applications where they may experience sudden shocks or impacts, such as automotive components, machinery parts, and construction materials. Higher impact strength indicates better resistance to fracture under dynamic loading conditions.
