Two rods are fixed between rigid massive walls and heated by the same temperature rise without bending. If $α_{1} : α_{2} = 2 : 3$ , equal thermal stresses require $Y_{1} : Y_{2} =$

Options:

Answer:

Solution:

$Y_{1} α_{1} Δ T = Y_{2} α_{2} Δ T$ .

$\frac{Y _{1}}{Y _{2}} = \frac{α _{2}}{α _{1}} = \frac{3}{2}$ .
