Joists support a floor and transfer their load to beams at each end of each joist. Joists are 2 ft on center and 30 ft long. If w, the load on the floor, is uniformly distributed and is 30 lb/ft2, what is the load on one joist? If the maximum flexural stress S in a joist is given by S = M/Z, where M is the maximum bending moment (pound-foot) and Z is the section modulus (cubic inches), what is the stress in a joist that has a section modulus of 50 in.3 and is 30 ft long?
