Simple Machine Calculators List

Lever Beam Length: Computes the length of a lever (beam) on one side of a fulcrum needed to lift an object based on the objects weight and the length of the beam on the other side of the fulcrum.

Leverage Lift Weight: Computes the weight that can be lifted using a lever based on the downward force and the length of the lever on either side of the fulcrum.

Fulcrum Position (x): Computes the position of 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.

Belt Length: Computes the length of a belt that goes around two pulleys of different diameters separated by a specific distance.two pulley system

Belt Speed: Computes the speed a belt travels based on the diameter of the pulley and the RPMs.

Pulley RPMs: Computes the RPMs of a pulley based on the speed of the belt and the diameter of the pulley.

2nd Pulley RPMs: Computes the RPMs of a second pulley in a two pulley system when the RPM and Diameter are known for one pulley and the diameter of the second pulley is also known.

2nd Pulley Diameter:- Computes the diameter of a second pulley in a two pulley system based on diameter and RPM of one pulley and the RPMs of the second.

RPM of 4th pulley on three shafts: Computes the RPMs of a fourth pulley on a three shaft system when the RMPs of the first shaft is known and the four diameters.

2nd Gear RPM: Computes the RPMs of a second gear when the RPM and number of teeth are known for the first gear, and the number of teeth are known for the second gear.

Pulley RPMs: Computes pulley RPMs from belt speed and pulley diameter.

Sum of Two Lengths: Computes the sum of two lengths (useful with lever calculations).

Second Gear Torque: Calculates the torque of a second gear when the torque and number of teeth are known for the first gear and the number of teeth of the second gear is known.

Leadscrew Torque (lift): Computes the torque required to lift a load with a square thread power screw assembly.
