Truss Spacing = 2'0" O.C.
Starting with the bottom chord load, we can calculate the PLF of the supported trusses.

Using the same process as in step #3, the calculated load is applied to the truss.
Use the following formula to calculate the PLF from the 1'0" overhang (the overhang span is not
divided by 2 because there is no other support, so the full load is supported by the knee wall):

Follow the same steps above the load from the overhang is applied to the top chord of the
truss.
