Why not make your own simple pulley from a construction set (or just homemade materials like cotton reels and string) and test it for yourself. There's no better way to understand how pulleys work. With a simple two-wheel pulley like this, it's easy to see that you have to pull the...
How does each granulator components work together? The belt and pulley are driven by the main motor. Then the materials will get into the drive shaft through the reducer. The open gear which is installed on the drive shaft works together with the large gear ring. The gear ring is fixed on...
Consider a pulley system with a mechanical advantage of 3 connected to a mass moving with a constant velocity. Calculate the mass of the object if the applied force is 15 N. If the rate at which a force does work increases, what happens to the power of the force?...
How exactly does a kettle work? Why does it take so long to boil? And how does it know when to switch itself off? Let's take a closer look!Photo: An electric kettle is a convenient way of making heat energy from electricity. It's a water heater, but it's also an energy ...
How do machines make work easier? Machines: Work is calculated by multiplying the force by the distance. There are two different kinds of machines: simple and complex machines. Simple machines include the pulley, lever and wedge, to name a few. Complex machines include two or more simple mach...
It turns out that the tumbler is one giant gear (or actually a pulley), and the motor drives a tiny pulley. Because of the ratio between the huge tumbler diameter and the tiny motor pulley diameter, no other gears are needed! You can see the thin belt wrapped around the tumbler in ...

How does a generator convert mechanical energy into electrical energy? How does tidal energy work? How do levers create energy if the conservation of energy does not allow energy to be created? How does kinetic energy work? How does a generator work? Explain the working of an electric generato...
The purpose of this balance is to conserve energy. With equal loads on each side of the sheave, it only takes a little bit of force to tip the balance one way or the other. Basically, the motor only has to overcome friction -- the weight on the other side does most of the work. ...
Unlike turbochargers, which use the exhaust gases created by combustion to power the compressor, superchargers draw their power directly from the crankshaft. Most are driven by an accessory belt, which wraps around a pulley that is connected to a drive gear. The drive gear, in turn, rotates th...
