The characteristics of ancient Egyptians are indicated by a set of artifacts and customs that lasted for thousands of years .When Egyptians built the pyramids , they needed to make some things to help them build pyramids easier. The Egyptians invented and used many basic machines, such as the ramp.

The ramp was built to help move the stones to
build the pyramids . Moving an object up an inclined plane required
less force than lifting it straight up, at a cost of an increase in the distance
moved. The ramps were made of earth, rubble and
mud bricks. The Ramp was not steep when its rose .And some ramps went around the
pyramids in a spiral.

As they build the pyramids , they needed to
find where north was. Because when the night was over, the sun must be on the
top of the pyramid. So they build a giant stone circle wall on the bottom of the
pyramids. A priest in the middle of the circle looked for a certain star that
went from east to west. The first thing that he needed to do was to draw lines
from east to west, than found north on half way between two
lines.

The pyramids were made of stones, but there
is only two kind of the stone be used, limestone and granite. The stone was cut
out of quarries, some far away from the site The stone cutter works so hard,
they used chisels to cut the stone out. It took a lot of muscle strength to act
the blocks of blocks of stone.[ which can weigh] . The stone blocks were floated
on barges on the Nile River.
