problem description
title="Beam w/Distributed Load Example Problem" nodes=5 elements=4

nodes
1 x=0    y=0     constraint=pinned
2 x=800          constraint=free     force=point
3 x=1600         constraint=free     
4 x=2800         constraint=roller
5 x=1600 y=-400  constraint=fixed

beam elements
1 nodes=[1,2] material=steel load=weight
2 nodes=[2,3] material=steel load=weight
3 nodes=[3,4] material=steel load=weight
4 nodes=[3,5] material=light load=light_wt

material properties
