Question 1

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

Question 2

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)

Question 3

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

Question 4

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

Question 5
