Temperature Measurement in Engineering

$DL = L \div \alpha \div DT$

$DL = L + \alpha + DT$

$DL = L - \alpha - DT$

$DL = L \cdot \alpha \cdot DT$ (correct)

$x = (\alpha_A \times \alpha_B) \cdot DT$

$x = (\alpha_A - \alpha_B) \cdot DT$ (correct)

$x = (\alpha_A + \alpha_B) \cdot DT$

$x = (\alpha_A / \alpha_B) \cdot DT$

$r = d\theta \cdot \alpha_B$ (correct)

$r = d\theta + \alpha_B$

$r = d\theta - \alpha_B$

$r = d\theta / \alpha_B$
