    So i know how to work out moments sorta but i am confused on what i am actually working out. So i get the answer in Newtons a Metre, but what does that mean exactly? And why is it that when i devide the other side of a levers length by this it gives me the force on the other side?

    You understand a force as how hard you push on something (and the direction of the push)?
    A moment or torque is how hard you twist something (with the direction of the twist).
    That's all there is to it.

    The units comes from the calculation - and that comes from how a linear force can be amplified by a lever.

    "Newtons a metre" should mean the same as "Newtons per metre", but torque is measured in Newton-metres. I.e. it's a number of Newtons multiplied by a number of metres, not divided by a number of metres.
