+71 When x pounds of force is applied to one end of a lever that is L feet long, the resulting force y on the other end is determined by the distance between the fulcrum (the lever's pivot) and the end of the lever on which the x pounds of force is exerted.
The formula relating the forces is xd= y(L-d) What formula can you use to find the length of the lever?
a.
L=(xd/y)+d
c.
L=(xd-yd)/y
b.
L=(xd+d)/y
d.
L=(yd)/x +d
