If the applied load is F=510 kN then what is the reaction at A? Let a positive reaction act to the nght The total length is still 5.1 m When the number of reaction forces is greater than the number of equilibrium equations, the system is statically indeterminate. Solving for the reactions requires some additional equations. These additional equations come from considering compatibility relationships (1 e, continuity of displacements and relationships between displacements and loads). Express your answer with appropriate units to three significant figures. > View Available Hint(s) For an axially loaded member, the compatibility relationship for the deflections can be written by setting the total relative axial displacement between the ends of the member to a known value. The load- HÀ Value Units NL gives another AE displacement relationship o = E %3D equation for the deflections. Once the internal normal force of each segment is written in terms of the end reactions and applied loads, there is enough information to solve for the reactions. Submit Part C- Load point for equal forces Consider the structure from Part B (Figure 2). What value of z will lead to equal reaction forces at A and B?
