RUVNL CE QUIZ 22

For a block shown below what will be change in volume?
(μ = 0.33)

Total volume of block is 6m³. And young’s modulus of elasticity is 200 GPa.

In symbol  x, y represent

S1- If U₁ is strain energy at Point 1, U₂ is strain energy at Point 2. If total t strain energy is U then relation between strain energy can be defined as

U₁ + U₂ = U

S2- As per superimposed theorem resultant energy can be algebraic sum of energy at different points (provided they have linear variation)
