This question was on my mechanics test but I skipped it. It seemed kinda crazy.

In the drawing is described a weightless beam AC connected to the wall through joint C. The beam is supported by two cables, BE and AD, connected to the wall. At the end of the beam at point A, acts a vertical force of 880 [N]

A) Calculate the tension in cables AD and BE

B) Calculate reaction at joint C

I'll spare you the rest of the equations, since no matter what view I'm looking at ...too many unknowns at sigma torque equation!
