For the truss structure Determine the governing equilibrium equation. Pf = KffU; + Pro Consider the applied loads and a distributed load wy = 5kN/m on member AC in the direction shown. Member AB is subject to a AT = -30C (cooled). Support C settles 8 = 0.01m down Solve for unknown displacements Determine the member force for each member Determine reactions at supports.
