1. The problem statement, all variables and given/known data
how mnay forces can you add to kep an object in equilibrium

2. Relevant equations

3. The attempt at a solution

is it infinite? and what would be the reason? It doesn't seem realistically possible??

Equilibrium means that the net force in both the horizontal and vertical compenents is 0.

so are you saying that there can be an infinite amount of forces acting on an object sp that it's at equilibrium?

If the object can handle an infinite amount of forces, than yes.

For example, there are 2 forces acting on an object horizontaly. One force is x N to the right, the other force is x N to the left, hence the net force in the horizontal component is 0, assuming there are no other forces acting upon it, it would not move, and be in equalibriam.

I'm thinking that ideally it would be infinite...but I'm somehow sure there are limitations...using calculus, one could show that infinite may not always lead to infinite. For example, if one were to cross a river, one would have to cross an infinite number of infinitesimal steps...but there is apparently some limited distance to it.
