# Can you have stress without strain?

## Can you have stress without strain?

Stress is the same as pressure. When you are under pressure, you are stressed! Stress can happen with out strain, but strain cannot happen without stress.

Is strain depend on stress?

Strain is the deformation of a material from stress. It is simply a ratio of the change in length to the original length. Deformations that are applied perpendicular to the cross section are normal strains, while deformations applied parallel to the cross section are shear strains.

### Why stress has units but not strain?

Strain is defined as extension per unit length. Strain has no units because it is a ratio of lengths. We can use the above definitions of stress and strain for forces causing tension or compression.

Is strain developed after application of stress?

Stress is the force applied to a material, divided by the material’s cross-sectional area. Strain is the deformation or displacement of material that results from an applied stress.

#### What is difference between stress and strain?

The key difference between stress and strain in physics is that stress is the force experienced by an object that causes a change in the object, whereas strain is the change in the shape of the object when stress is applied.

Which comes first stress or strain?

Stress strain curve is a behavior of material when it is subjected to load and frm SN curve we can say stress generates only when there is deformation (or it is about to deform) caused by some mechanical or physical forces. Therefore Strain always comes first then only stress generates.

## Does stress or strain produce stress?

Is It The Stress That, Produces Strain Or Strain Produces Stress? Strain is independent of stress. One easy way to remember is that those quantities present along X axis are independent.

What is stress and strain with example?

For example, a stress on a rubber band produces larger strain (deformation) than the same stress on a steel band of the same dimensions because the elastic modulus for rubber is two orders of magnitude smaller than the elastic modulus for steel.

### Why strain is more important than stress?

When as elastic body gets strained under the influence of external forces, a reaction force develops inside the body. It means that only when strain is produced in a body, a stress is developed within it. So, elastic strain is more fundamental than stress.

Why strain is independent and stress is dependent?

In stress-strain curve as strain or the deformation is independent and comes as result of the externally applied force, so it is taken in X-axis. Where as Stress comes in order to resist the deformation in terms of Resisting force. so it is dependent on strain and comes in Y-axis.
