`W _"(lift mass)" = "F" * "y" "/" "x" `
Enter a value for all fields
The Weight Lifted by Leverage calculator (`W = F * y/x`) 
computes the mass (W) that can be lifted by the use of a lever when the downward mass / weight and the two lengths (x and y) on either side of the fulcrum are known.
INSTRUCTIONS: Choose units and enter the following:
- (F) Downward Force (weight) opposite the fulcrum from the object.
- (y) Length of Beam on opposite side of fulcrum from the object (see diagram).
- (x) Length of Beam on object's side of fulcrum (see diagram)
Weight Lifted by Lever (W): The calculator computes the mass/weight (W) in kilograms. However this can be automatically converted to other mass or weight units via the pull-down menu.
The Math/Science
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.
Mechanical Leverage Functions
- (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
