For the following computer problem, any appropriate software may be used. Input prompts should fully explain what is required of the user (the program should be user-friendly). The resulting output should be well labeled and self-explanatory.
Repeat Problem, except now assume the beam to be a hot-rolled steel wide-flange shape. User input will be span length, uniform load intensity, and the following dimensions for the shape: overall depth, thickness and width of the flange, and the web thickness. Assume the unit weight of the steel to be 490 pcf. Calculate I by approximating the cross section with three rectangles.
Problem
Write a program that may be used to calculate the maximum bending stress and the maximum horizontal shear stress for a simply supported single-span timber beam that carries a uniformly distributed load. User input is to be uniformly distributed load intensity, span, and the nominal dimensions of the cross section. (Use nominal dimensions for the calculations and assume a unit weight for the timber of 35 pcf.)
