What is stress multiplied by strain?

Stress is thus obtained by multiplying strain by the Young’s modulus. When a material receives a tensile force P, it elongates in the axial direction while contracting in the transverse direction.

What is the formula of stress and strain?

stress = (elastic modulus) × strain. stress = (elastic modulus) × strain. As we can see from dimensional analysis of this relation, the elastic modulus has the same physical unit as stress because strain is dimensionless.

What is the value of relation between stress and strain?

Hooke’s law explains the relationship between stress and strain. According to Hooke’s law, the strain in a solid is proportional to the applied stress and this should be within the elastic limit of that solid.

What is transformation of stress and strain?

One key reason for stress or strain transformation is that the strains are normally measured in the laboratory along particular directions, and they must be transformed into a new coordinate system before the relevant stresses can be re-calculated.

What is strain in physics class 11?

Strain is the measurement of how much an object is stretched or deformed due to the stress developed in the object. Strain occurs when external force is applied to an object. Complete step by step answer: When the deforming force is applied to an object, the object changes its shape.

What is meant by strain in physics?

Strain is simply the measure of how much an object is stretched or deformed. Strain occurs when force is applied to an object. Strain deals mostly with the change in length of the object.

What is stress in physics class 11?

Stress:- Stress is the restoring force per unit area. Whenever we apply an external force on the body to change its shape there is a restoring force that develops in the body in the opposite direction.

Does stress produce strain?

Stress can cause strain, if it is sufficient to overcome the strength of the object that is under stress. Strain is a change in shape or size resulting from applied forces (deformation).

What is Hooke’s law for stress and strain?

Hooke’s law states that the strain of the material is proportional to the applied stress within the elastic limit of that material. When the elastic materials are stretched, the atoms and molecules deform until stress is applied, and when the stress is removed, they return to their initial state.

What are principal stresses and strains?

The three stresses normal to shear principal planes are called principal stress, while a plane at which shear strain is zero is called principal strain.

Why do we perform stress transformation?

We need to calculate the normal and shear stresses perpendicular and parallel to the joint. Therefore, we need to rotate, or transform, the coordinates associated with the force P to the direction associated with the angle of the glued joint. Then, we can evaluate the stresses along these new directions, x’ and y’.
