The image above represents engineering stress. Two essential parameters, force (F) and Area (A), are needed to calculate engineering stress.

The formula for calculating engineering stress:

Stress = F/A

Where:

F = Force
A = Area

Given an example;
Find the engineering stress when the force is 12 and the area is 4.

This implies that;

F = Force = 12
A = Area = 4

Stress = F/A
That is, Stress = 12 / 4
Stress = 3

Therefore, the engineering stress is 3 Nm^-2.

Calculating the Force when the Engineering Stress and the Area are Given

F = Stress x A

Where:

F = Force
Stress = Engineering Stress
A = Area

Let’s solve an example;
Find the force when the engineering stress is 10 and the area is 2.

This implies that;

Stress = Engineering Stress = 10
A = Area = 2

F = Stress x A
So, F = 10 x 2
F = 20

Therefore, the force is 20 N.

Calculating the Area when the Engineering Stress and the Force are Given

A = ^F / _Stress

Where:

A = Area
Stress = Engineering Stress
F = Force

Let’s solve an example;
Find the area when the engineering stress is 8 and the force is 24.

This implies that;

Stress = Engineering Stress = 8
F = Force = 24

A = ^F / _Stress
That is, A = ²⁴ / ₈
A = 3

Therefore, the area is 3m².
