Question

what is the difference between stress and pressure

​

Answer 1

Answer:

according to physics

pressure is the external force acting on a body whereas stress is the internal force resisting the deformation of body.

Answer 2

Answer:

Explanation:

Difference between Stress and Pressure

Stress

Stress can be defined as the amount of force being exerted per unit area.

Stress can be represented as (strain) / (Young’s modulus)

Stress can only be exerted on solids.

Stress on the other hand can be either a positive or a negative force, this can be represented as Stress= – F/A.

Stress is a unique property of the material.

Pressure

Pressure can be defined as the amount of force applied per unit area.

Pressure can be mathematically represented as (force) / (area)

Pressure on the other hand can be exerted on both liquids and gases.

Pressure is a positive unit and can be represented as F/A

Pressure on the other hand is a unique property of thermodynamics
