Enter 3 out of 4 below:

F1 x F2 d

Given F1 = 10, F21 = 20, Distance from F1 to fulcrum (x) = 5

Calculate Lever Length (d)

F1x = F2(d - x)

F1x = F2d - F2x

Add F2x to both sides:

F1x + F2x = F2d - F2x + F2x

F1x + F2x = F2d

x(F1 + F2) = F2d

Divide each side of the equation by F2:

 x(F1 + F2) F2
 =
 F2d F2

Cancelling F2 on the right side, we get:

 d  = x(F1 + F2) F2

Plug in our numbers and simplify:

 d  = 5(10 + 20) 20

 d  = 5(30) 20

 x  = 150 20
