          3.18 Using the method of Section 3.5, determine the axial stress in each of the bar elements shown in Figure P3-18.

$E = 30 \times 10^6 \text{ psi}$
$A = 2 \text{ in}^2$
$L = 60 \text{ in.}$
$v_1 = 0$
$v_2 = 0.02 \text{ in.}$
$l_1 = 0$
$l_2 = 0.01 \text{ in.}$

3.18 Using the method of Section 3.5, determine the axial stress in each of the bar elements shown in Figure P3-18.

E = 30 × 10^6 psi
A = 2 in^2
L = 60 in.
v1 = 0
v2 = 0.02 in.
l1 = 0
l2 = 0.01 in.

Step 1

Given: - Initial length of each bar element (L) = 60 in - Change in temperature (ΔT) = 0.01 in - Coefficient of linear expansion (α) = 0.02 in/in/°F The change in length (ΔL) of each bar element can be calculated using the formula: ΔL = α * L * ΔT Substituting Show more…
