| DETERMINATION OF MOVEMENTS IN STATICALLY DEFINABLE SYSTEMS. CALCULATION FOR HARDNESS |
| One of the problems of resistance of materials is the evaluation of the rigidity of the structure the degree of distortion under the action of the load. If the beam under load bends strongly, then during its operation there will be difficulties. |
| Calculation of the stiffness of a structural element having a bar shape consists in determining the largest angular and linear elastic displacements of its cross sections at a given load and comparing them with permissible, depending on the purpose and operating conditions of this element. In other words, the stiffness condition can be expressed by the inequality: |
 |
Where  and  - linear angular displacement of the considered section arising under the load, and  and  - permissible displacement values assigned by the constructor. |
