The Attempt at a Solution

I have half of it done, but the numbers are beginning to get outrageously rediculous... I just want to double check the numbers with someone... my colleagues at school have a program "Truss Analysis Module" program that can calculate the forces on the members and show whether it is in tension or compression. Does anyone know what program this is? It is a free one apparently T_T


Anyways, I just want to double check with the values I currently got

a = 36.457kN ( Compression )
f = 84.562kN ( Compression )
e = 72.096kN ( Tension )
b = 109.878kN (Tension)
g = 74.837kN ( Compression )

I started from the very left side of the truss

It's due tomorrow :( really tough week with all the exams and tests T_T

I'm starting to come in from the right end, and it's starting to match up.. I think I'm doing it correctly ^^. I like to talk to myself thanks guys.
