A) using singularity functions, write a single equation for m(x) along the beam. hint: use the constant ‘w’ for 30 lb/in and ‘ l’ for 120 in.; it will make the algebra in the next couple of parts much easier.
b) find the reactions at a and b.
c) find the deflection of the beam at x=120 in. if it is an s-beam (s24x80 structural steel; e = 29 x 106 psi; i = 2100 in4).
