The **Downward Force** calculator * Lever with beam (x+y) and fulcrum.*computes the mass/weight (F) required that can lift an object with a lever and fulcrum.

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

- (
**W**) Mass Lifted - (
**y**) Length of Beam on the downward force side of the fulcrum (see diagram). - (
**x**) Length of Beam on Mass' side of the fulcrum (see diagram)

**Downward Force on a Lever (F)**: The calculator computes the mass/weight (F) in kilograms. However this can be automatically converted to other mass or weight units via the pull-down menu.

**(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
