Learning Goal: To solve for forces in statically indeterminate bars with axial lesads.

Solking for the reactions requires some additional equations. These additional equations come from considering compatibility relationships $($i$.$e$.,$ continuity of displacements and relationships between displacements and loads$).$

For an axially loaded member, the compatibility relationship for the deflections can be written by setting the total relative axial

For an axially losded mermber, the compatibility relationship for the deflections can be writter by seting the idtal relative axial

equation far the deflections. Once the internal narmal force of each segment is witten in terms of the end reactions and applied laads there is encugh information to salve for the reactions.

there is enough information to salve for the reactions.

Part A $-$ Force with a known deflection

Part C $-$ Load point for equal forces

Consider the structure from Part B $($Fiqure $2).$ What value of $x$ will lead to equal reaction forces at A and $B$

Express your answer in feet to three algnificant figures.
