Question: Develop a computer program to calculate the safe vertical end reaction of an end notched beam. The program input should include the allowable shear stress, depth of notch, and distance over which the notch is beveled. Using your program, solve Problem.
Problem: 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?
