Marvelous Strain Formula Class 11
Stress is a tensor quantity.
Strain formula class 11. A graph is plotted between the stress which is equal in magnitude to the applied force per unit area and the strain produced. Units of stress are the same as units of pressure Pascals symbol. Its unit is Nm2 or Pascal and dimensional formula is ML-12T-2.
Hookes law explains the relationship between stress and strain. B -p ΔVV Where p hydraulic stress ΔVV hydraulic strain. The graph helps us to understand how a given material deforms with increasing loads.
It is a curve between stress and strain. Class 11 Physics Mechanical Properties of Solids. The fractional change in configuration is called strain.
Deformation is known as the change of the shape of an object by applications of force. σ is the stress measured using Nm2 or Pa. Consider a rubber ball and if it is dipped in the pond Due to the pressure of water from all directions force acts on the ball as a result the.
Poissons Ratio - Longitudinal Strain and Lateral Strain. A is the area of cross-section measured in m2. - ive signs show that the increase in pressure results in decrease in volume.
Class 11 Physics Mechanical Properties of Solids. Its unit is Nm 2 or Pascal and its dimensional formula is ML. An elastic band of length 5 cm is stretched such that its length increases by 2 mm.
