Answer:
Total elongation will be 0.012 m
Explanation:
We have given diameter of the cylinder = 2.1 mm
Length of wire
So radius
Load F = 280 N
Elastic modulus = 207 Gpa
Area of cross section
We know that elongation in wire is given by , here F is load, L is length, A is area and E is elastic modulus
So
