The box beam is constructed from two boards that are fastened together using nails spaced along the beam every 2 in. If each nail can resist a shear force of 50 lb a) determine the shear force "V" that can be applied to the beam without causing failure of the nails. b) determine the maximum shear stress at NA due to shear force "V" 2 in. 12 in. 9.5in.
The beam is constructed from three boards. If it is subjected to a shear of V = 5 kip, determine the maximum allowable spacings of the nails used to hold the top and bottom flanges to the web. Each nail can support a shear force of 500 lb.
ESP 3-6: The simply supported beam is built up from three boards by nailing them together as shown. The wood has an allowable shear stress of Tallow=1.9 MPa, and an allowable bending stress of allow=8.4 MPa. The nails are spaced at s = 75 mm, and each has a shear strength of 1 kN. Determine the maximum allowable force P that can be applied to the beam. А. -1m- 25 mm 25 mm 200 mm 125 mm

Review An engineered wood beam (Figure 1) will replace a portion of a structural wall as part of a house renovation. The beam can be modeled as a simply supported beam with a span L = 18 ft and an uniform distributed load w = 810 lb/ft . The beam is to be constructed as an I-beam with nails securing the flanges to the web. The flanges are 6 in wide and 1 in thick. The web has depth 18...
Learning Goal: To calculate the shear stress at the web/flange joint in a beam and use that stress to calculate the required nail spacing to make a built- up beam. A built up beam can be constructed by fastening flat plates together. When an l-beam is subjected to a shear load, internal shear stress is developed at every cross section, with longitudinal shear stress balancing transverse shear stress. If the beam is built up using plates, the fasteners used must...
