A simply supported beam is 0.6 feet long, and has a distributed load of 8.9 kips/ft pointing in the negative y direction along the entire beam. First- find the maximum moment in the beam? HINT: You should draw the beam. QUESTION: If the y distance from the neutral axis to the furthest fiber in tension is = -5 inches, and the moment of inertia of the beam is 100 in4, then what is the bending stress in the beam? in psi? Give answer to 1 decimal point, and no units, such as 1250.1 (not 1250.1 psi)
