i don't understand how you can end up with about 10n downward and 17n forward with the real total force being 20n.
it feels like you are getting more force out than you are putting into the system..

I guess it has something to do with each direction sharing the force across different directions? i.e. a percentage of the downward force is simultaneously contributing to the forward force and vice versa?

I guess I'm just having trouble visualizing the relationship on a physical level between the two vectors and the total force in the system.
