Lever Systems Formula Calculator

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)

The Lever Equation is as follows:

F1x = F2(d - x)

Multiply the right side of the equation out:

F1x = F2d - F2x

Add F2x to both sides:

F1x + F2x = F2d - F2x + F2x

Cancelling F2x on the right side, we get:

F1x + F2x = F2d

Factor out x:

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

Lever Length (d) = 7.5
