lever (downward force)

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.

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
