Copper has a modulus of elasticity of 110 gpa. a specimen of copper having a rectangular cross section 15.2 mm × 19.1 mm is pulled in tension with 44,500 n force, producing only elastic deformation. calculate the resulting strain.

Explanation:

As we know by the formula of elasticity that

now we have

Area = 15.2 mm x 19.1 mm

now we also know that force is given as

here we have

stress = Force / Area

now from above formula we have

i would think it's food chain

double the distance = divide strength by 4
