Consider a simply supported beam of length L. The beam
experiences a parabolically varying distributed load that varies
from 0 at the left support, to a maximum w at midspan, and back to
0 at the right support. The beam has stiffness properties EI. Give
a mathematical equation that gives the value of the distributed
load intensity at any distance z along the beam in terms of w, L
and z. Draw the SFD and BMD of the beam, giving...
