A cuboid ABCDEFGH is an isotropic with ax = 1×10–5 / 0C, ay = 2×10–5 / 0C, az = 3×10–5 / 0C. Coefficient of superficial expansion of faces can be –
A
bABCD = 5 × 10–5 / 0C
B
bBCGH = 4 × 10–5 / 0C
C
bCDEH = 3 × 10–5 / 0C
D
bEFGH = 2 × 10–5 / 0C
Answer
bCDEH = 3 × 10–5 / 0C
Explanation
Solution
b = ax + ay
