Chapter 6 | Solution to Problems | Shearing Stresses in Beams and Thin-Walled Members

Problem 6.1: Three full-size 50 x 100-mm boards are nailed together to form a beam that is subjected to a vertical shear of 1500 N. Knowing that the allowable shearing force in each nail is 400 N, determine the largest longitudinal spacing s that can be used between each pair of nails. Problem 6.6: The beam shown is fabricated by connecting two channel shapes and two plates, using bolts of 3/4-in. diameter spaced longitudinally every 7.5 in. Determine the average shearing stress in the bolts caused by a shearing force of 25 kips parallel to the y axis. Problem 6.35: An extruded aluminum beam has the cross section shown. Knowing that the vertical shear in the beam is 150 kN, determine the shearing stress at (a) point a, (b) point b. Problem 6.38: The vertical shear is 1200 lb in a beam having the cross section shown. Knowing that d = 4 in., determine the shearing stress at (a) point a, (b) point b.
