Question: A nominal 2 X 10-in. (50 X 250-mm) floor joist has the end notched on the bottom to a depth of 3 in. (76.2 mm). The notch is beveled over a distance of 6 in. (152 mm). If the allowable shear stress of the joist is 185 psi (1275 kPa), what is the maximum safe vertical reaction at the end of the joist?
