Solution to Problem 593 | Spacing of Rivets or Bolts in Built-Up Beams

Problem 593
A box beam, built up as shown in Fig. P-593, is secured by screws spaced 5 in. apart. The beam supports a concentrated load P at the third point of a simply supported span 12 ft long. Determine the maximum value of P that will not exceed fv = 120 psi in the beam or a shearing force of 300 lb in the screws. What is the maximum flexural stress in the beam?
