Question: Assume for Problem that the same load is applied on the bar. To what temperature must the wires be heated before the load is entirely carried by the middle wire?
Problem: Three vertical steel wires are loaded as shown. At a temperature of 68°F, the bottom ends of the wires were at the same elevation with no load on the bar. A downward load of 500 lb was then centrally applied on the bar and the temperature was increased by 100 degrees. What load is carried by each wire assuming the load bar remains horizontal?
