Rods of lengths $L_{1}, L_{2}$ have coefficients $α_{1}, α_{2}$ with $L_{1} α_{1} = L_{2} α_{2}$ . Both are heated by $Δ T$ . Select correct statements.

Options:(select one or more)

Answer:

B, C

Solution:

$Δ L_{i} = L_{i} α_{i} Δ T$ . Equal products imply equal changes, so final difference remains $L_{1} - L_{2}$ . B,C.
