The beam has a rectangular cross section and is made of wood having an allowable (transverse) shear stress of 200 psi. Determine the maximum shear force V that can be permitted by the cross section of the beam.
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...
To analyze two built-up members that have the same geometry but are fastened differently, determine the maximum applicable shear force on each cross section, and determine the adjustment in spacing between the weaker member’s fasteners that would allow the member to support the equivalent maximum shear force of the stronger member. The two cross sections shown below, (a) and (b), are subjected to a vertical shear force as shown. The members are fastened by nails that can support a load...
