How do you calculate a force of a object that is not accelerating

[assuredlonewo]

I would like to know how to calculate the force of an object that is not accelerating, for example, If I were push on a wall, neither me or the wall would move because the net force would be zero, but how would I calculate the force if I am trying to put on the wall.(I do not want the net force)

Welcome to PF.

Sometimes that type of force can be calculated (like the force between a book and a table on which it is sitting) and sometimes it can't. The force you described can't be calculated, only measured.

The force on a book on a table can be calculated because g (or G) was measured previously (historically).

If you push the wall by simply leaning on it, you can imagine replacing yourself by a leaning post of equal weight and calculate the horizontal component caused by gravity (the part touching the floor is a pivot point).

How can you measure it?

How can you measure it?

Place a scale between your hands and the wall.
