← HistoryWhich mechanism allowed ancient Egyptians to move massive stone blocks for pyramid construction?
A)Leverage using inclined planes✓
B)Buoyancy using inflated bladders
C)Cryogenic freezing of the ground
D)Magnetic levitation of stone
💡 Explanation
When moving massive blocks, Egyptians used inclined planes because this reduced the required force using mechanical advantage, translating small force over long distance to move heavy objects. Therefore leverage results, rather than buoyancy, freezing, or levitation, which require different technologies.
