\nUse the four-step plan:
\n1. \u00a0Equilibrium<\/em> – FBD of BCD and writing down the equilibrium equations.
\n2. \u00a0Load\/deflection\/thermal\u00a0<\/em> – \u00a0Write down the load\/deflection equation for each of the two elements: e = FL\/EA + \u03b1\u0394TL<\/em>.
\n3. \u00a0Compatibility<\/em> – Use geometry to relate the member elongations to the displacements of B and D. Focus on using the correct signs in these equations.
\n4. \u00a0Solve<\/em> – Count the number of equations and the number of unknowns. If you have sufficient equations, solve for the axial forces in the members, and from those calculate the stresses. If not, go back to Steps 1-3 to see what you are missing.<\/p>\n
