1. Перекладіть текст. Mechanical Properties of Metals and Alloys

Strength. - The strength of material is the property of resistance to external loads or stresses without incurring structural damage.

The strength of metals and alloys depends upon two factors, namely, the strength of the crystals of which the metals are constructed and the tenacity of adherence between these crystals.

Stress and Strain. - A stress is the force within a body which resists deformation due to an externally applied load. If this load acts upon a surface of unit area, it is called a unit force and the stress resisting it a unit stress.

When n external force acts upon an elastic material, the material is deformed and the deformation is in proportion to the load. This distortion or deformation is strain.

Elasticity. - Any material subjected to an external load is distorted or strained. Elasticity stressed materials return to their original dimensions when the load is released if the load is not too great. The property of regaining the original dimensions upon removal of the external load is known as elasticity.

The Nature of Elasticity.- The elasticity of a metallic substances is a resistance of its atoms to separation or compression or rotation about one another, and thus is a fundamental property of the material. So elasticity is demonstrated as a function of atomic forces.
