Homework Equations



F = Fu

The Attempt at a Solution



Okay, so um I'm having trouble with this particular question. Normally if the wires were all straight, I'd have no problem solving this. But for this question, the wire seems to go from B to A to C, creating this corner/joint looking thing.

How do I solve with this thing? Kind of confused how I can utilize the angles as well... thanks the help in advance. I don't need answers or anything, but I just need a push to get started. The CAB corner joint thing is really throwing me off here. Not sure how to proceed.

Thanks again.

hi mneox! :smile:

the weight at A is in equlibrium, so that gives you an equation relating the tensions in AB and AC :wink:
