Pyramid Ramp Physics: Sledge Friction & Wetted Sand (2D)

2D sledge-hauling lab: real Amontons–Coulomb friction on a ramp, the documented friction-halving effect of wetting the sand ahead of the sledge, and exactly how many haulers it takes to move a multi-tonne block.

This 2D companion turns the 3D Ancient Egypt scene's pyramid backdrop into a working physics lab: it computes the real Amontons–Coulomb pulling force needed to drag a stone-laden sledge up a ramp (F = μmg·cosθ + mg·sinθ), applies the friction-halving effect of wetting the sand ahead of the sledge documented in 2014 physics research and shown in the Djehutihotep tomb painting, and shows exactly how many haulers pulling a sustainable 250 N each are needed to move the block — or whether the given team falls short.

⚙ Under the hood

2D sledge-hauling lab: real Amontons friction on a ramp (F = μmg·cosθ + mg·sinθ), the documented wetted-sand friction reduction, and how many workers at ~250 N sustained pull it takes to move a multi-tonne block.
