Answer:
What are Internal Forces?
Internal forces are produced from the external forces acting on structure members such as poled, beamd or columnd. Generally, we have three types of internal forces: axial, dhear and moment. Axial force, sometimes called 'normal force,' is a compression or tension force acting aligned with the extension of a structure member. Shear force is a force acting in a direction perpendicular to the alignment of the member. Moment force, lastly, is a turning result of a force multiplied by the distance from its acting location to the turning point. The number of these components varies in one-dimensional, two-dimensional and three-dimensional cases. Now the questions are what each of these components do and how to calculate these internal forces.
Equilibrium
When a structure member such as a pole, beam or column is in equilibrium, it means that it isn't moving as it is supposed to be. Therefore, the combination or resultant of all the external forces applied to the member equals zero. In fact, the internal forces maintain the equilibrium of a structure member in different directions.
