What is an Axial Force? Definition: A force is said to be an axial force if applied along the body's axis. In engineering and physics, it is essential to identify the type of force acting on a body. An axial force can be either a tensile or a compressive force. If the axial force tends to pull the body apart, it is a tensile force.
