The given answers don't work for Fcos(θ)=600, no. But that could mean either Mastering Engineering flubbed or, more likely, I flubbed the starting equations.
Says The homework. Because I've already gotten this question wrong, and the answers were displayed. I'm asking about this question here so I know what to do when this sort of problem comes up again.
Homework Statement
So we have a force of unknown magnitude acting on these struts at an angle θ measured from strut AB.
The component of the force acting along AB is 600lb, and the magnitude of the force acting along BC is 500lb.
If Φ = 60°, what is the magnitude of F and the angle θ...
