Enter the yield stress, moment of inertia, distance from the force to the bend, and the distance from the neutral axis (typically thickness), to determine the rod bending force.

Rod Bending Force Formula

The following equation is used to calculate the Rod Bending Force.

F = S * I / (y*d)

  • Where F is the rod bending force (N)
  • S is the yield strength of the material (N/m^2)
  • I is the moment of inertia (kg-m^2)
  • y is the distance from the force to the bend point (m)
  • d is the distance from the neutral axis (thickness) (m)

What is a Rod Bending Force?

Definition:

A rod bending force is a type of force that causes an object to flex or bend. This force can either be applied directly to the object or cause the object to flex through direct contact with another object.

The amount of force needed to bend an object varies depending on its size, strength, and resistance to deformation. A rod bending force is also known as tensile stress.

How to Calculate Rod Bending Force?

Example Problem:

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

First, determine the tensile strength. In this case, the tensile strength of the material is 50.

Next, determine the moment of inertia. The moment of inertia of the rod is 10.

Next, determine the distance from the force to the bending point. In this case, the distance is 2m.

Next, determine the distance from the force to the neutral axis. This is measured to be .5 m

Finally, calculate the rob bending force using the formula above:

F = S * I / (y*d)

F = 50*10 / (2*.5)

F = 500 n
