Question

Explain a stress-strain curve for a mild steel specimen in tension and show the prominent points on it. ,d ekbYM LVhy Liksflesu esa ruko d s fy, izfrcy fod`fr curve dh O;k[;k djks rFkk eq[; fcUnqvksa dks n"kkZvksAA mild steel rod 20 mm diameter and 1.5 m length is subjected to an axial pull of 20 kN. If the modulus of elasticity material is 2x105 N/sq. mm, determine (i) the stress, (ii) strain and (iii) elongation of the bar.

Answer 1

Answer:

By now, we know that the stress and strain take different forms in different situations. In this article, we will understand the relationship between stress and strain by looking at the Hooke’s law and the stress-strain curve.
