problem 1: A truss is shown in the given figure. find out the horizontal deflection of joint D produced by both the load and fabrication error (bar AE is 40mm too long). For all bars, area A = 1000 mm2, E = 200 GPa.
problem 2: Use the Force Method to find out all the support reactions in the given figure. A is a fixed support and B and C are roller supports. EI is constant.
