The **Fulcrum Position** calculator computes the distance (**x**) from the object to the fulcrum based on the length of the beam (**L**), the mass of the object (**W**) and the downward force (**F**).

**INSTRUCTIONS**: Choose your preferred units and enter the following:

- (
**F**) Downward force (weight) opposite the fulcrum from the object. - (
**W**) Mass (weight) of the object being lifted. - (
**L**) Total length of the beam (L = x+y in diagram)

**Fulcrum Position (x):** The calculator returns the length in meters. However this can be automatically converted to other length units via the pull-down menu.

A lever is a simple machine where the ratio of the product of the lengths and forces on opposite sides of a fulcrum are equal as is represented in the following equation:

where:

- W = Weight or Mass lifted
- x = length of lever on the weight side of the fulcrum
- F = downward force
- y = length of lever on the downward force side of the fulcrum

**(y) Beam Length:**computes the required length of a beam above the fulcrum for a lever to raise a weight (**W**) based on the downward weight applied (**F**) and the length below the fulcrum (**x**).**(W) Lift Weight:**computes the weight that can be lifted with a lever based on the length of the beam (**y**) above the fulcrum, the length (**x**) below the fulcrum and downward weight applied (**F**).**(x) Fulcrum Position**: computes the length from the object to the fulcrum needed in a lever to lift a weight (**W**) with a downward force (**F**) with a beam of length (**L**), where L = x + y (see below).**(F) Downward Force or Weight:**computes the mass needed to create the downward force (F) to raise the object with a lever.**L = x+y**: computes the sum of two lengths
