Given F_{1} = 10, F2_{1} = 20, Distance from F_{1} to fulcrum (x) = 5

Calculate Lever Length (d)

##### The Lever Equation is as follows:

F_{1}x = F_{2}(d - x)

##### Multiply the right side of the equation out:

F_{1}x = F_{2}d - F_{2}x

##### Add F_{2}x to both sides:

F_{1}x + F_{2}x = F_{2}d - F_{2}x + F_{2}x

##### Cancelling F_{2}x on the right side, we get:

F_{1}x + F_{2}x = F_{2}d

##### Factor out x:

x(F_{1} + F_{2}) = F_{2}d

##### Divide each side of the equation by F_{2}:

##### Cancelling F_{2} on the right side, we get:

d = | x(F_{1} + F_{2}) |

| F_{2} |

##### Plug in our numbers and simplify:

##### Final Answer:

Lever Length (d) = **7.5**
