Member B is subjected to a compressive force of 650 lb. If A and B are both made of wood and are 3/8 in. thick, determine to the nearest ¼ in. the smallest dimension d of the support so that the average shear stress along section C does not exceed τ allow = 300 psi.
determine to the nearest ¼ in. the smallest dimension d of the support so that the average shear stress along section C does not exceed τ allow = 300 psi.
Q2a) Member B is subjected to a compressive force of 800lb. if A and B are both made of wood and are inch thick. Determine to the nearest inch the smallest dimension h of the horizontal segment so that it does not fail in shear. The average shear stress for the segment is allow=350 psi.
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...
