+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 |
