Question

Determine the young modulus of grass rod of diameter 30mm and length is 300mm. which is subjected to a tensile load of 50KN. When extension of the rod is equal to 0.2mm.​

Answer 1

Answer:

This Strain equation computes engineering strain from the simplest definition, where Strain is simply a ratio of the change in length to the original length. The is:

ε = ΔL / L

where:

ε is

ΔL is the change in elongation.

L is the original length

So 0.3/250 is 0.0012 or 0.12%.
