a 2\"x2\"x10\'-0\" long steel bar is stretched by a tensile force (F) of 10,000

Question

a 2"x2"x10'-0" long steel bar is stretched by a tensile force (F) of 10,000 lbs, as shown. Find the tensile stress, tensile strain, and total elongation of the steel bar.

In lecture my professor said that:

Tensile stress is Force/Area

Tensile strain is the deformation / length

Elastic Modulus is tensile stress / tensile strain

and the deformation is Force*length / elastic modulus*Area

but I'm not sure how to calculate for the tensile strain and the deformation

a 2"x2"x10'-0" long steel bar is stretched by a tensile force (F) of 10,000 lbs, as shown. Find the tensile stress, tensile strain, and total elongation of the steel bar.

Explanation / Answer

You must have been given Elastic modulus/ Young's modulus for the question to be solved...
