Lever Windlass Mechanism Explained: How It Works, Diagram, Parts, Formula and Uses
Compare the ideal lever-to-drum radius ratio and reciprocal hand-to-rope travel. The animation shows rope take-up and the holding pawl during handle reset.
Capstan or Vertical Windlass Mechanism Explained: How It Works, Parts, Diagram, and Uses
Explore rope friction around a vertical capstan. Adjust tail tension, friction coefficient and turns to calculate an ideal impending-slip tension limit.
Drum and Rope Conversion Mechanism Explained: How Winch Drums Convert Rotation to Linear Pull
Explore winding-drum rotation and tangential rope travel. Calculate line speed, travel per turn and ideal pull from effective diameter, rpm and shaft torque.
Winch Mechanism Explained: Diagram, Parts, Gear Reduction and Line Pull Calculator
Compare ideal hand-crank torque and winch line pull from gear ratio and drum radius. The results are calculations of ideal force, not lifting ratings.
Wheel and Axle Mechanism: How It Works, Formula, Diagram, and Real-World Uses Explained
Explore a wheel and axle rotating together. Compare ideal mechanical advantage and the distance travelled at each radius during one revolution.
Capstan (form) Mechanism Explained: How It Works, Eytelwein Equation, Diagram and Uses
Explore rope contact around a vertical capstan and the ideal limiting tension ratio. Adjust tail tension, wraps and friction; distinguish the result from equipment capacity.
