Maximum Force Formula

For uniform axial stress, the following equation gives force at the entered stress. Other modes use friction, spring, pressure, shear or ideal Euler-buckling models.

MF = YS × A
  • Where MF is the nominal force at the specified uniform stress (N)
  • YS is the yield strength of the material (N/m^2)
  • A is the area the force is acting on (m^2)

To calculate the maximum force, multiply the yield strength by the area.

What is a Maximum Force?

Definition:

Yield strength times cross-section area estimates nominal axial yield load under uniform stress. It is not a certified maximum capacity: buckling, shear, connections, imperfections and other failure modes may govern. Safety factors and applicable design rules require separate verification.

How to Calculate Maximum Force?

Example Problem:

The following example outlines the steps and information needed to calculate Maximum Force.

First, determine the yield strength of the material. In this example, the yield strength of the material is found to be 500 N/m^2.

Next, determine the area the force is acting on. For this problem, the area the force is acting on is 2 m^2.

Finally, calculate the Maximum Force using the formula above:

MF = YS * A

MF = 500 * 2

MF = 1000 N
