Question

A rigid triangular frame is pivoted at C and
held by two identical horizontal wires at points A
and B (see figure). Each wire has an axial rigidity
EA =120 kips and coefficient of thermal expansion
α =12.5 X 10-6 / °F .
(a) If a vertical load P = 500 lb acts at point D,
what are the tensile forces TA and TB in the wires
at A and B, respectively?
