Question

The modulus of elasticity of steel is ____________ pounds per square inch.

(a) 6,500,000

(b) 10,000,000

(c) 30,000,000

(d) 1000,00

This question was posed to me in final exam.

This interesting question is from Aircraft Materials topic in division Testing Aircraft Materials of Aerospace Materials & Processes

Answer 1

The correct choice is (c) 30,000,000

For explanation: The modulus of elasticity of a material is used in determining the normal elongation of a material. The modulus of elasticity of steel is 30,000,000 pounds per square inch. For aluminium alloys, it is 10,000,000 Psi and for magnesium it is 6,500,000 psi.
