Stress calculator

If you want to determine the force acting per unit area of an object, you can use our stress calculator.

In physics, stress is defined as a restoring force acting on the per unit area of an object. The restoring force acting on an object is equivalent to the magnitude of the applied deforming force but opposite in direction. The SI unit used to determine the stress is Pascal (equivalent to N/m2). It is not a scalar or vector quantity, but it is a tensor quantity. A Greek letter that represents stress is "σ".


Formula of Stress Calculator

To determine the value of stress applying to an object, you can instantly find it by jumping to our free online calculator. Or to find it manually, you can use the formula listed below:

\[\sigma = \frac{F}{A}\]


σ = Stress

F = Restoring force (Measured in Newton (N))

A = Area of an object (measured in m2)


For a more precise and clear understanding of a concept, let us solve an example below:

Suppose an object has an area of 30m2 and is drawn by 100 N of force. Find out the stress applied to an object.

Given data

Force = F = 100 N
Area = A = 30m2

To Find

Stress applied to an object = ?


To find out the stress applied to an object, we will use the formula listed below;

\[\sigma = \frac{F}{A}\]

Putting values in the formula:

\[\sigma = \frac{100}{30}=3.33N/m^2\]
