In engineering mechanics, internal forces are actions that change the state of motion of a body. They can be represented mathematically or graphically. 

Here are some types of internal forces:
Axial force: Also known as the normal force, this is a compression or tension force that acts along the extension of a structure member.
Shear force: This force acts perpendicular to the alignment of the member.
Moment force: This is the turning result of a force. 

Other types of internal forces include:
Compression: A squeezing force applied to a material.
Tension: A force that causes a substance to stretch.
Torsion: A force that twists or turns.
Bending: The process of bending a straight material into a curved shape. 

The equation for calculating internal forces within a structure is d 2 M d x 2 = V. 
To determine internal forces, it is necessary to know about the positive and negative sides of the section
