Forces in Trusses: Tips for Finding Forces in Members

[TSN79]

Look at the bottom problem at this page:

http://physics.uwstout.edu/StatStr/statics/StatII/statp22t2.htm

When I have found the force Ay (the y-component of the reaction force at point A), does that in this case mean that the force in member AE is then equal to this? If so, then the force in member EF is equal to Ex, correct? Or?

Any tips appreciated...

The first part is right about AE but you can't assume EF=Ex because there is also member BE framing into the joint you have to analyze.

Ah, yes. I've got it now, thanks haynewp!
