    Force and fulcrums
    If a 15.0 N force is applied to a level at a distance of 10.0 m from the fulcrum then how much force is needed at 25.0m from the fulcrum to balance the 15.0 N force?

    Find the anticlockwise and clockwise moments, from



    The moments from both distances from the fulcrum have to be equal so that the system is balanced. So, equate your equations!
