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
:
x(F
1
+ F
2
)
F
2
=
F
2
d
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:
d =
5(10 + 20)
20
d =
5(30)
20
x =
150
20
Lever Length (d) =
7.5
What is the Answer?
Lever Length (d) =
7.5
