Pulleys reduce the force required to lift heavy objects.
Machines? Almost everything that was done in the ancient world was done by hand... The only thing that aided us humans machine wise would possibly different types of pulley systems to move and hoist things around. I think it is rather fascinating that they was able to do all that they did and how they accomplished tasks that was carried out upon a daily life... But, then again... Slavery was another big part in the ancient world... So, technically all the wonders we see today was either done by either one of two different types of people... 1) People that was loyal to do tasks for the leadership or 2) People that opposed that leadership would be forced into slavery
Anubis was the ancient Egyptian god of embalming, and tester, protector, and guide to the dead in the Duat (underworld).
no
they use arrows
Nup.
It could be used to pull ships onto land and to get water from a well. Archimedes invented the compound pulley in ancient Greece.
The simple pulley was invented in ancient times by an unknown person. The compound pulley was invented by Archimedes.
pulley for what?
yes , yes it is
the pulley was invented in ancient Sicily around 250 BC. The ancient Egyptian wooden four lobe pinion pulley was used to construct the Giza Pyramids around 2600 BC. This pulley surrounds its load and is unlike anything in the modern world. It operates with a mechanical advantage of 2.8 (MA=2.8) on the CLASS 2 lever principle. When hoisted the pulley with load rotates and climbs stepped structures with positive engagements of pulley lobes with steps. This is earliest machine known using "rack and pinion" mechanical technology. Google four lobe pinion pulley
The exact date of when pulleys were first used by humans is not known, but evidence suggests it was utilized in ancient Mesopotamia around 1500 BCE. Pulleys were later further developed by the ancient Greeks and Romans for various tasks such as lifting heavy objects and constructing buildings.
Fixed Pulley and Compound Pulley.
To remove a pulley, you typically need to use a pulley puller tool. First, release tension on the belt connected to the pulley. Then, follow the specific instructions for your vehicle or equipment to use the pulley puller to gently remove the pulley without damaging surrounding components.
It would depend on what you want to use the belt and pulley for
No, a pulley does not use friction. Pulleys are simple machines that use a wheel and axle to redirect the force applied to them. Friction is not necessary for a pulley to work properly.
remove all belts,tensioners etc, remove pulley bolt, use HARMONIC BALENCER PULLEY to remove - DO NOT USE NORMAL PULLEY REMOVER - must be pulled from center of pulley not from outer edge
Nobody Knows for sure I think Ancient Greece, it was discovered by Archimedes
