Prob. 3.7-2. Elements (1) and (2) were supposed to fit ex- actly between the rigid walls at A and C in Fig. P3.7-1. However, element (1) was manufactured a small amount, 8 L. too long. However, an ingenious technician was able to compress element (1) and insert it in the space between A and B (indicated by dashed lines). (a) Determine expres- sions for the stress o, induced in element (1) and the stress o induced in element (2), and (b) determine the amount t by which element (2) is shortened when element (1) is forced into the dashed-line position. Assume 8L in calculating the flexibility coefficient f. Solve Parts (a) and (b) of Prob. 3.7-1 for the following rod systems: System S1: E₁ = E. E, = 2E, and System S2: E₁= 2E. E, E. Discuss the difference in the stresses induced in the rods in these two cases. = A₁-A, A = 1.5A (1) -L+3 P3.7-1, P3.7-2 (2)
