Mechanical & Hydraulic calculators
Force, speed, and load calculators for hydraulics, rigging, and mechanical systems.
- Hydraulic Cylinder Force and Speed CalculatorCylinder push force = pressure × piston area (π ÷ 4 × bore²); speed = flow × 231 ÷ (60 × area) in inches per second.Inputs: Bore diameter, Rod diameter, Pressure
- Pulley Mechanical Advantage CalculatorIdeal mechanical advantage equals the number of rope parts supporting the load; the pull needed is load ÷ advantage, plus friction losses.Inputs: Load weight, Rope parts supporting the load, Friction loss per sheave
- Sling Angle Load CalculatorSling tension per leg = load ÷ (number of legs × sin of the angle from horizontal); a 30° angle doubles the tension in each leg of a two-leg sling.Inputs: Load weight, Number of legs carrying the load, Sling angle from horizontal
