The typical Young's modulus of steel is A 275-310 GPa B 145 - 170 GPa c) 195 - 210 GPa D) 225 - 240 GPa

A cylindrical specimen of some metal alloy having an elastic modulus of 101 GPa and an original cross-sectional diameter of 3.6 mm will experience only elastic deformation when a tensile load of 2430 N is applied. Calculate the maximum length of the specimen before deformation if the maximum allowable elongation is 0.41 mm. i mm

A mild steel flat of width 120 mm and thickness 10 mm is bent into an arc of a circle of radius 10 m by applying a pure moment 'M'. If E is 200 GPa, then magnitude of the pure moment 'M' will be

An alloy steel specimen of 30 mm diameter with a gauge length of 200 mm is load tested. It has extension of 0.16 mm under a load of 85 kN. Load at elastic limit is 160 kN. Young's modulus of the specimen in GPa O 127 O 143 O 150 O 172
