For jake . Set is chiding you so you dont sound dumb . Rather, you should learn to use the library's resources by yourself rather than continuously asking dumass questions.
Egyptians were pretty proud of their construction methods, they had carvings and drawings all over showing examples of huge drag lines and sledges used to drag huge rocks (over 200 T) on ramps .(See some of the drawings of the construction of pyramids and accretion "theory)
A hunk of flat quarried limestone has a sp gravity that would yield a ground pressure of about(for an 80 m^^ ground surface) 925 kg/cm^^
(I kept it at deciml numbers). SO overcoming that frictional force would need a running force of a bit more than half of that (Ill say about 500 kg/cm^^)(MAX can run these to see if Im close). Really, that does NOT require aliens , just good pathways qnd lotsa people.
The drawing at GHOZER shows a huge sledge with maybe 1000 guys on lines and dudes dumping water along the sledges pathway to reduce even more of the friction. (Apparently sledges worked better than wheels for huge block) It stands to reason, wheels have a much smaller contact surface so spot pressures would be incredible to resolve at such small areas.the question. They had oxen and workers so Even if Im off by 100%,
the forces needed to overcome friction arent out of the realm of possibility by using our own planetary resources.
Now Im assuming that your 50 T rock was correct because Ive seen blocks of dolerite and granites that were moved by Egyptians, all with weights of 200 METRIC TONS at a 2.8 Sp gravity (a bit heavier and dense than Limestones)
Im more amazed at how thy built these things WITHOUT construction drawings.(A human invention we take for granted, but we generally credit Leonardo duh Vinci for inventing several thousand years AFTER the 5th dynasty)
