Thankyou very much. This is perfect and exactly what I needed.

I hope this will be an easy one to answer that I could just use a little help with. I have an L shaped bar where 'X' is on a flat surface. The pivot point is the circle. Can someone help me with a formula to calculate the force needed at point 'b' , given a certain force applied at point 'a'...
