1. Carry out an approximate analysis of the truss in Figure P13.10 by treating it as a continuous beam of constant cross section. As part of the analysis, evaluate the forces in members DE and EF and compute the reactions at A and K.
2. Use an approximate analysis of the continuous truss in Figure P13.11 to determine the reactions at A and B. Also evaluate the forces in bars a, b, c, and d. Given: P = 9 kN.
