(1) A simply supported steel beam is 30' long and subjected to a uniform distributed 1.3 kips per foot. What is the minimum required section modulus for this beam if we do not want its maximum stress to exceed 50 ksi?

(2) What is the minimum inertia of the beam in the previous question if we do not want it to deflect more than 1/2" ?
