Question

Define stress energy and derive the equation.....physics ​

Answer 1

Answer:

The stress–energy tensor, sometimes stress–energy–momentum tensor or energy–momentum tensor, is a tensor quantity in physics that describes the density and flux of energy and momentum in spacetime, generalizing the stress tensor of Newtonian physics.

Answer 2

Answer:

Hey Buddy here's ur answer

Strain energy is defined as the energy stored in a body due to deformation. The strain energy per unit volume is known as strain energy density and the area under the stress-strain curve towards the point of deformation. Regarding young's modulus E, the strain energy formula is given as, U = σ2 / 2E × V
