Machines Toolkit - Quick Calculators

Essential calculators for Mechanical Advantage, Efficiency, and Unit Conversions.

Mechanical Advantage (MA)

AMA = 4.00

Ideal Mechanical Advantage

IMA = 4.00

Efficiency Calculator

Efficiency = 87.5%

Unit Converter

Quick Reference Formulas

Lever
IMA = Effort Arm / Load Arm
Pulley
IMA = Number of Supporting Strands
Inclined Plane
IMA = Length / Height
Wheel & Axle
IMA = Wheel Radius / Axle Radius
Gears
Gear Ratio = Driven / Driver teeth
Efficiency
Eff = (AMA / IMA) × 100%
