Equation of lt= l0[1 + α (T2 -T1)] find out the dimensions of the coefficient of linear expansion α suffix.
(a) M0L0T1K1
(b) M0L1T1K1
(c) M1L1T0K1
(d) M0L0T0K-1
Explanation:
ℓ1 = ℓ0[1 + α(T2 – T1)]
∴ α = [(ℓ1/ℓ0) – 1] [1 / (T2 – T1)]
= [(ℓ1 – ℓ0) / ℓ0][1 / (T2 – T1)]
Dimensions of α = {[L] / ([L][k])} = [k–1] = [M0L0T1K–1]
