I have solved a number of example questions referring to Trusses. I have one where the forces do not balance correctly when I check through. A difference with this truss is that there is a couple applied to the truss. I have been using the method of Joints to do the working out. Does the presence of a net couple mean that I have to do something different? Can anyone point me to an example where the calculations are done on a Truss with a couple applied to it?
