1. The problem statement, all variables and given/known data Alright so I have an object being pulled from two sides at an angle like the picture below. I want to figure out a third force that can be added to keep the object in the middle of the two sides. Are the directions of the components I drew correct? (There is an actual problem for this, I thought I'd put a more general question though) 2. Relevant equations Vector addition and subtraction 3. The attempt at a solution I found the horizontal and vertical components of both forces. I then subtracted the horizontal forces from each other because they were going in opposite directions, and added the horizontal vectors because they were going in the same direction. To find the third force, I used the equal but opposite vertical and horizontal forces and found the third net force.... I hope I explained this right :S Please help me out by telling me if I'm doing this right?
