Hints<\/strong><\/em>:
\nFor Part A<\/span><\/em> – Use the four-step plan:
\n1. \u00a0Equilibrium<\/em> – FBDs of the connectors and writing down the equilibrium equation for each.
\n2. \u00a0Load\/deflection<\/em> – \u00a0Write down the load\/deflection equation for each element: e = FL\/EA<\/em>.
\n3. \u00a0Compatibility<\/em> – Starting from the left end, add up the elongations for the three elements. This sum equals the displacement of end H, uH<\/sub>. What is uH<\/sub> in this case?
\n4. \u00a0Solve<\/em> – Count the number of equations and the number of unknowns. If you have sufficient equations, solve. If not, go back to Steps 1-3 to see what you are missing.<\/p>\n

For Part B<\/em> <\/span>\u00a0– Use geometry to relate the elongations of the two elastic members. Be careful with the signs in relating elongations to displacements.<\/p>\n
