- When we apply deforming force on a body, the shape of the body changes and body is said to be strained. Strain is measured as the ratio of change in configuration to the original configuration.

Intermolecular Force
In a solid, atoms and molecules are arranged in a way that neighbouring molecules exert a force on each other. These forces are intermolecular forces.
Elasticity
A body regains its original configuration (length, shape or volume) after you remove the deforming forces. This is elasticity.
Perfectly Elastic Body
A perfectly elastic body regains its original configuration immediately and completely after the removal of deforming force from it. Quartz and phosphor bronze are the examples of nearly perfectly elastic bodies.
It is the ratio of the internal force F, produced when the substance is deformed, to the area A over which this force acts. In equilibrium, this force is equal in magnitude to the externally applied force. In other words, The SI Unit of stress is newton per square meter (Nm-2).In CGS units, stress is measured in dyne-cm-2. Dimensional formula of st...
It is the ratioof the change in size or shape to the original size or shape. It has no dimensions, it is just a number.
Hooke’s law states that, within elastic limits, the ratio of stress to the corresponding strain produced is a constant. This constant is called the modulus of elasticity. Thus,
Stress-strain curves are useful to understand the tensile strength of a given material. The given figure shows a stress-strain curve of a given metal. 1. The curve from O to A is linear. In this region, the material obeys the Hooke’s Proportional limit law. 2. In the region from A to C stress and strain are not proportional. Still, the body regains...
Q: A and B are two steel wires and the radius of A is twice that of B, if we stretch them by the same load, then the stress on B is: 1. Four times that of A 2. Two times that of A 3. Three times that of A 4. Same Sol: A) Since stress is inversely proportional to the area, and the area is proportional to the square of the radius, then we can write: ...
What is strain? Define different types of strains. When we apply deforming force on a body, the shape of the body changes and body is said to be strained. Strain is measured as the ratio of change in configuration to the original configuration.
3 days ago · Stress and strain have a straight proportional relationship up to an elastic limit. The relationship between stress and strain is explained by Hooke's law. Hooke's law states that the strain in a solid is proportional to the applied stress, which must be within the solid's elastic limit.

shearing stress. As a result of applied tangential force, there is a relative displacement ∆x between opposite faces of the cylinder as shown in the Fig. 8.1(b). The strain so produced is known as shearing strain and it is defined as the ratio of relative displacement of the faces ∆x to the length of the cylinder L.
