A pulley is a simple machine that has a grooved wheel that holds a rope or a cable. This is used to lift heavy loads. It is also known as sheave or drum.
A pulley
A pulley isn't a kind of simple machine, it is a simple machine
An example of simple gears is the chain, chain-wheel and free-wheel sprocket as used on a single geared bicycle. More complicated gearing is the modern bicycle's derailleur system of multiply chain-wheels, a cluster of sprockets, a chain, and gear changer mechanism.
That would most likely be a pulley. A pulley is essentially a wheel on an axle that usually has a groove in the middle of its circumference that holds a rope, cable, belt, or chain. Pulleys are used to transmit motion rotationally and apply force in the direction of said motion. Two or more pulleys makes a tackle. Hope this is what you were looking for.
Yes, a grooved wheel with a rope or chain running through the groove is considered a pulley. Pulleys are commonly used to transmit force, typically used to lift or lower objects.
no belt, no chain, it has cog wheels its a chain
You have the chain and sprockets which i believe could be classified as a pulley system, and then of course you have the wheels, and the pedals may count as levers, but im not sure about those.
1. By pushing the heavy object with pulling 2. Using simple lever, chain/rope and pully, rollers, wheels, poles, tacks etc.
The chain is wrapped around a cogwheel, which could be described as a pulley.
Not the whole part of the bike but the pedals are levers a kind of simple machine it uses the levers to apply force to the sprocket sprocket is a wheel and axle ,another simple machine,that uses gears to move the chain.
Sprockets are the toothed wheels that the chain run over.
