Q1:

The Young's modulus of elasticity of steel, is

A 150 KN/mm2

B 200 KN/mm2

C 250 KN/mm2

D 275 KN/mm2

ANS:B - 200 KN/mm2

The Young's modulus of elasticity of steel typically ranges from about 200 to 210 GigaPascals (GPa), which is equivalent to 200,000 to 210,000 MegaPascals (MPa) or approximately 200,000 to 210,000 kiloNewtons per square millimeter (kN/mm²). Therefore, among the options provided, the closest value to the typical range is: 200KN/mm^2
