Question

4. A steel wire is acted upon a load of 10 N. Calculate the extension
produced in the wire, if the strain energy stored in the wire is 1.1 x 10-3 J *​

Answer 1

Answer:

Strain energy= 1.1 × 10^-3 F(load)=10N Formula:- Strain energy=1/2×(load)×(extension) The above formula is taken from the derivation of the formula Strain energy per unit vol =1/2×stress×strain Sol:- 1.1 × 10^-3=1/2×10×extension Extension = 2.2×10^-4 Have attached the textbook pic of the formula.
