JEE Main 2022 — Mechanical Properties of Solids Question with Solution

JEE Main 2022 (26 Jun Shift 1)

Question

The elastic behaviour of material for linear stress and linear strain, is shown in the figure. The energy density for a linear strain of 5×10-4 is _____  kJ m-3. Assume that material is elastic upto the linear strain of 5×10-4,

Correct answer
25

Step-by-step explanation

From the above graph, we can find that when the strain is 5×10-4 the stress is 100 MPa. We know that energy density is

U=12×stress×strain⇒U=12×100×106×5×10-4

⇒U=2.5×104 J m-3=25 kJ m-3
