A blog where I post solutions to the mechanics and statics problems that I encounter. Also many mastering engineering problems will be seen, so users of that program may find this blog interesting. The course uses the Hibbeler Statics textbook and some of the subjects covered include: Cartesian vectors, force resultants, force equilibrium, particle equilibrium, Hooke's Law, vector decomposition, etc. More to be added as those problems and topics are encountered.

The mast is subjected to the three forces shown. Determine the coordinate direction angles of F1 so that the resultant force acting on the mast is zero.
F2 and F3 have no X components so I dont see why F1 in your solution has an X component. F1 should be only on the ZY plane, because it doesnt need to balance anything on the X axis, therefore the angle the F1 makes with the X axes should be 90 degrees
