Question
A statically determinate pin-jointed frame is shown in Figure P10.4. The cross-sectional area
of members AG, BG, CF, CG, FG and EF is equal to 400 mm?. The cross-sectional area of all
other members is equal to 100 mm². Assume E = 205 kN/mm? and a = 12 × 10-6 / °C. All
members are subjected a decrease in temperature equal to 20°C. Using the data given,
determine the value of the horizontal deflection at joint F.
