Question

Elastic Modulus of Steel is __________

(a) 1.5 x 10^9 N/mm^2

(b) 2.0 x 10^5 N/mm^2

(c) 2.0 x 10^5 N/m^2

(d) 1.5 x 10^9 N/m^2

This question was posed to me in homework.

This is a very interesting question from Properties of Steel in portion Materials, Structures and Specifications of Design of Steel Structures

Answer 1

Correct choice is (b) 2.0 x 10^5 N/mm^2

For explanation I would say: Elastic modulus = Stress/Strain. As per IS 800-2007, elastic modulus of steel is 2.0 x 10⁵ N/mm².
