Four firefighters hold a square net, one at each corner. Each person exerts a force of 190 N whose line-of-action passes through a point just below the center of the net and makes an angle with the vertical of 50°. What is the net force the firefighters exert on the net?
The Attempt at a Solution
I've tried splitting the problem into four vectors and solving from there, but I cannot seem to get the correct answer. Also, don't the forces cancel out?
I guess what I'm trying to say is that I'm lost. Any indication on how to start this one would really be appreciated.
