A cylindrical specimen of brass that has a diameter of 20 mm, a tensile modulus of 110 GPa, and a Poisson’s ratio of 0.35 is pulled in tension with force of 40,000 N. If the deformation is totally elastic, what is the strain experienced by the specimen?
(A) 0.00116
(B) 0.00029
(C) 0.00463
(D) 0.01350

0.00116

Explanation

The tensile modulus is the measure of the elastic deformation that a material has undergo.

While elastic strain  is define as form of strain in which a body return to its original length after the removal of the force .

Strain s expressed as

Where e is the strain, A is the area, F is the applied force and E itensile modulus

From the data given,

Force, F=40,000

Area=πr^2

and the tensile modulus E=110GPa

If we insert values we arrive at

Hence the strain experienced by the material is 0.00116
