Chapter 6.5, Problem 45P
A beam consists of five planks of 1.5 × 6-in. cross section connected by steel bolts with a longitudinal spacing of 9 in. Knowing that the shear in the beam is vertical and equal to 2000 lb and that the allowable average shearing stress in each bolt is 7500 psi, determine the smallest permissible bolt diameter that can be used.

Three 1 x 18-in. steel plates are bolted to four L6 x 6 x 1 angles to form a beam with the cross section shown. The bolts have a 78-in. diameter and are spaced longitudinally every 5 in. Knowing that the allowable average shearing stress in the bolts is 12 ksi, determine the largest permissible vertical shear in the beam. (Given: Ix= 6123 in4.)
A timber beam AB of length L and rectangular cross section carries a single concentrated load P at its midpoint C. (a) Show that the ratio Tm/ m of the maximum values of the shearing and normal stresses in the beam is equal to h/2L, where h and L are, respectively, the depth and the length of the beam. (b) Determine the depth h and the width b of the beam, knowing that L = 2 m, P = 40 kN, 7m = 960 kPa, and om = 12 MPa.
(14) A beam of I-section is 2 in. wide and 4 in. deep with all sections 1/2 in. thick. It is supported at
points 5ft. apart, and carries a concentrated load of 400 lb at a distance of 2ft from the left support.

of 0, 1, and 2 in. from the neutral axis.
