I need to verify a couple of unknown forces in a truss, attached image (all individual trusses are 300mm in length)
Determine the forces in trusses shown.
The Attempt at a Solution
This is a lab and i've used a telescopic gauge with a calibration chart to obtain a rough value of what the forces should be, (missed too many classes on Framworks damnit!)
From Left to Right Box, Left 100N Tension, Right 187.5N Compression RL is 163.5 N Rr is 130.8N
Even is i have a parallel worked example it would be enough.
