If diametric strain 0.035 for a sphere then volumetric strain of a sphere

If length of bar is 10 mm and thermal stress is σ₁. If length of bar is changes to 20 mm and corresponding thermal stress is σ₂ then be

(∝ = 12 × 10^-6°C, T = 25°C, E = 210 GPa)

A₁ = 200 mm²

E₁ = E₂ = 210GPa

A₂ = 300 mm²

L = 100 mm

P = 120 kN

If A₁, E₁ are area and young’s modulus of bar 1 . A₂, E₂ is area and young’s modulus of bar 2 . Then total deflection in composite bear will be

Total number of independent elastic constant for Homogeneous and Isotropic material will be

For a beam under general loading condition, Number of internal forces are
