1) The strength of materials is one of the fields of building science.

2) The strength of materials only studies bearing reactions of structural elements.

3) A deformation takes place when the material is in a state of stress.

4) Strain expresses the deformation change.

5) Shear stress causes opposing forces to act along parallel lines of action.

6) Yield strength, compressive strength, tensile strength, fatigue strength and impact strength are not the terms in the strength of materials.

8. Соотнесите фрагменты предложения так, чтобы смысл высказывания не был нарушен

One of the fields of building science	is the change in geometry when stress is applied in the form of force loading
To design a mechanical part, a structure,	is the strength of materials.
Deformation of the material	compressive, tensile and shear.
There are three kinds of stresses	it is initially to imagine the forms and geometrical skeleton.
Strain or reduced deformation	is a mathematical term to express the trend of the deformation change among the material field.
