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 |
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 |
Final Answer:
Lever Length (d) = 7.5
What is the Answer?
Lever Length (d) = 7.5
