Question

An anisotropic material has coefficient of linear expansion a, 2a and 3a along the three co-ordinate axis. Coefficient of cubical expansion of material will be equal to –

• A. (a) 2a
• A. (b) $\sqrt[3]{6}\alpha$
• A. (c) 6a
• A. (d) None of these

Answer 1

(c)

For anisotropic material

g = a + 2a + 3a = 6a
