A rigid bar of weight W = 750 lb hangs from
three equally spaced wires: two of steel and one of
aluminum (see figure). The diameter of the wires is
1/8 in. Before they were loaded, all three wires had
the same length.
What temperature increase ΔT in all three
wires will result in the entire load being carried
by the steel wires? (Assume ES = 30 x106 psi,
αS =6.5x10-6 /°F , αa =12x10-6 /°F
