A 82 ft steel bar undergoes a stretch of 087 in in an axial

A 8.2 ft steel bar undergoes a stretch of 0.87 in in an axial direction. What is the strain? Use three significant figures (four if your the first non-zero digit of your answer is 1)

Solution

Solution :

Strain is nothing but a measure to see how much the material has deformed when compared to the original length.

Strain = change is length/ Original length Original length = 8.2ft = 98.4 in

Strain = 0.87 / 98.4 = 0.008841
