A pulley. The wheels aren't necessarily grooved; you just need a way to prevent to rope from slipping off the wheel.
pulley
Pulley-a simple machine that uses grooved wheels and a rope to raise, lower, or move a load.Lever- a stiff bar that rests on a support called a fulcrum which lifts or moves loads.
wheel and axle: in motor and wheels to make it move
A wagon wheels uses the wheel of a wagon (not the tyre part through, wire, and string or rope to make an easy and simple pulley.
A sewing machine is a compound machine. To make up a sewing machine, the simple machines you need to use are: an inclined plane, definitely a lever, lots of screws, wheels and axles, a wedge..................... you basically have to use all the simple machines!
Neither of them are simple machines. A vaccum cleaner is composed of several simple machine, (I don't really know what) and a bicycle is composed of a wheel and axle (the two wheels), pulleys (the gears), and levers (Brake handles and pedals).
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.
Block and tackle
no its a grooved wheel with a rope running along the groove the above answer is wrong because it is the definition of a pulley. Yes that is true. A wheel and axle is a simple machine consisting of two wheels of different sizes that rotate together.

A simple machine made from wheels and ropes is a pulley.
A wheel and axle is a simple machine. But it has another simple machine enet. Which one is it? A lever
yes, of course
Well, its a simple machine and they are meant to make things easier. Also, it creates less friction on the ground
A multi Vee pulley
I'm thinking that it's a compound machine. There are four wheels, then millions of screws that hold it together.
