1.Repeat Prob. 2–28, except that the design situation is failure by excessive deflection, and it is desired to minimize the weight. 2. For an axially loaded rod, prove that b = 1 for the
Eb_r guidelines in Fig. 2–16. 3. For an axially loaded rod, prove that b = 1 for the
Sb_r guidelines in Fig. 2–19. 4. For a cantilever beam loaded in bending, prove that b= 1_2 for the
Eb_r guidelines in Fig. 2–16.
