Diameter and extension of a bar under a load?

A round bar of 20mm diameter is subjected to a tensile force of 150kN. Young’s Modulus 200 GN/m^2.
What must be the diameter of the middle portion if the stress in the middle portion is 215 MN/m^2.

What is the total extension of the bar under the given Load?

Young’s Modulus (YM) is defined as Stress / Strain

Stress is the Force divided by the area.

Strain is the extension due to a stress divided by the length over which the extension is measured.

You know what the stress has to be (215MN/m^2) and you know the Force 150kN, so you can easily work out the area required.

The problem is that you do not know over what length the extension is measured.

Assuming that the length is L then the strain = Stress / YM (=215MN/m^2/200GN/m^2) and the extension is L * Stress / YM.

MAke sure that you have everything in the same units.
