Write the MATLAB code and use the function linsolve() to solve the system of linear equations. Thank you! l Truss A truss is a structure that typically consists of 1. All straight members 2. connected together with pin joints 3. connected only at the ends of the members 4. and all external forces (loads&reactions) must be applied only at the joints. The weights of the members may be neglected. The basic building block of a truss is a triangle. Large...
Learning Goal: To solve for forces in statically indeterminate bars with axial loads. Consider a new structure, where the thickness of the bar is reduced to 32.5 mm from C to B (it is still square) (Figure 2) and <= 3.75 m. If the applied load is F - 370 kN , then what is the reaction at ? Let a positive reaction act to the right. The total length is still 6 m Express your answer with appropriate units...

To solve for forces in statically indeterminate bars with axial loads.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 (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 displacement between the ends of the...
