1. For the bar assemblages shown in Figures P3–2 through P3–11, determine the nodal displacements,..
1. For the bar assemblages shown in Figures P3–2 through P3–11, indicate the nodal demolitions, the forces in each part, and the reactions. Use the trodden cacophony order for these problems.
2. Indicate the cacophony matrix for the bar part with end nodes and midlength node shown in Figure P3–13. Let axial demolition u = a1 a2x a3x2. (This is a higherorder part in that clarify now varies linearly through the element.)
