Why Ramps Make Heavy Loads Easier to Move
An inclined plane doesn't reduce the work needed to lift a load — it spreads that work over a longer distance so the force required at any moment is smaller. Here's the math and the trade-offs.
The Physics of the Screw: From Archimedes to the Modern Bolt
A screw is an inclined plane wrapped around a cylinder, which is why a small turning effort can generate enormous clamping force — and why threads hold their position without slipping.
