Floating
-Floating means an object remains on the surface of a liquid without sinking.
Buoyancy, or thrust (upthrust), is an upward force exerted by fluid on an object fully or partially immersed. Pressure increases with depth due to the weight of the overlying fluid.
A block of limestone will sink when dropped into water because the density of limestone is much greater than the density of water. A limestone block would have been placed on a barge or boat to displace the weight of the water equal to the stone’s weight and keep the limestone block on the water’s surface.
In my theory, the barges used for stone transport are not wooden planks roped together with a flat top surface. Instead, the barges were built from wood, similar to an open rectangular box, with a specific depth and flat bottom for better stability on the water. All barges were built to meet certain specifications, keeping the sluices’ dimensions to a minimum.
2. Shaduf
-A shaduf operates on the same principle as a lever.
Lever
Torque (Moment)
Torque equals Force times Distance
