| External forces are called the forces of interaction between the structural element under consideration and the bodies associated with it. |
| If the load is distributed over the surface of the body or its part, then this load is called distributed. |
| In the design scheme, the load distributed over the surface (Fig. 1.2) results in a plane coinciding with the longitudinal axis, resulting in a load distributed along the line. |
| The measure of such a load is its intensity q - the value of the load per unit length. Dimension - N / m. |
| The resultant distributed load is numerically equal to the area of its plot and is applied at the center of its gravity. |

| In addition to toro, there are loads in the form of a concentrated moment (a pair of vultures). There are several ways to depict moments (Fig. 1.3). |
 |
| Fig. 1.3 |
| Then M is the torque (Fig. 1.4). |

| This is the image of a vulture going to us. |
 |
| This is how the force coming from us is depicted. |
