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...

2. The frame shown consists of a very stiff steel beam with a wide-flange beam (W33 X 200), welded rigidly to two vertical channels (C8 X11.5). Assume that the mass of the channels is small compared to the mass of the beam. The area moment of inertia of each channel about its centroidal bending axis is 1.3 in. An eccentric exciter weighting 50 lb is attached to the beam, which weighs 2,000 lb, and is used to excite the frame....

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...

The beam shown in the figure consists of a W360 79 structural steel wide-flange shape [E = 200 GPa; 1 = 225 x 100 mm"]. For the loading shown, determine: (a) the reactions at A, B, and C. Enter a positive value for a reaction force that acts upward on the beam, or a negative value for a reaction force that acts downward. (b) the magnitude of the maximum bending stress in the beam. Enter a positive value for the...
