Question

Prove that strain has no
unit from its
its mathematical expression ? ​

Answer 1

Answer:

Explanation:

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. When the applied force is released, the whole system returns to its original shape. It is usually denoted by U.

U = Fδ / 2

Where,

δ = compression,

F = force applied.

When stress σ is proportional to strain ϵ, the strain energy formula is given by,

Strain energy formula

Where,

σ = stress

V = volume of body

Regarding Young’s modulus E, the strain energy formula is given as,

U = σ2 / 2E × V.

Where,

σ = stress,

E = Young’s modulus,

V = volume of body.

Answer 2

Explanation:

The speed of light is 186,000 miles per second. How would you express this number in scientific notation?
