What is the difference between stress and pressure?
Stress& pressure: Stress is the internal factor (force) operating across a cross-sectional region within such a substance, although pressure would be the force exerted per unit area commonly utilized inside a liquid.
Difference between stress and pressure:
Stress | Pressure |
1.The internal resistive force to deformation per unit area would be described as stress. | 1.The amount of force delivered per unit area is described as pressure. |
2.The pressure will not be developed due to stress. | 2.Stress will be developed due to pressure. |
3.Stress can be either a positive or a negative force. | 3.The pressure is always a positive force. |
4.Pressure is exerted externally. | 4.Stress is exerted internally. |
5.Stress may be tensile, compressive, and shear. | 5.The pressure would always be compressive. |
6.The quantity of stress at different points throughout different directions varies. | 6.The amount of pressure at a location remains constant in all directions. |
