A rigid bar ACDB is pinned at end A and supported by vertical wires of the same material
(E-210GPa) and equal cross section area (A-80 mm²) at point C and point D as shown below. The
coefficient of thermal expansion of steel is alpha = 12x106/°C. The dimensions are
0.8m, d=2.4m and L = 3.0m. The vertical force P = 10 kN. With this information answer the
