Most of the electricity in the power grid is generated by powerful turbines spinning around. Why don't these turbines slow down from the work they do moving electrons? What are the 3 types of pulleys? How do you calculate the mechanical advantage of a pulley?
Types of Pulleys There are three types of pulleys. Each pulley system depends on how the wheel and ropes are combined. Fixed Pulley It is the simplest form of pulleys. Simple pulleys have their axles fixed in place and cannot be moved. The rope moves in the groove of the pulley, but th...
Continuously variable transmissions, or CVTs, function the same as an automatic transmission with one significant difference - there are no gears, instead operating through the use of belts and pulleys. Sensors are equipped with the transmission that feeds information to an onboard computer, adjusting...
A pulley works by changing the direction of the force needed to lift an object. By using a pulley, the force needed to lift the object is spread out over multiple ropes, making it easier to lift. What are the two types of pulleys? The two types of pulleys are fixed...
What are the types of mechanical weathering? What is a reciprocating internal combustion engine? A knife is what type of machine? What are some examples of electromagnets? What are three examples of measurement devices in exercise science?
Paddle agitation systems have a shaft that runs the length of the tank with steel paddles mounted on it. The paddles are driven by belts and pulleys that are connected to the engine, or by a hydraulic system. The big advantage to paddle agitation systems is their ability to mix any type ...
With one cone attached to the engine and the other attached to the wheels, the position of the bands determines the ratio between the two pulleys. Because there are no set gear ratios within the transmission, a CVT will always be at the optimal ratio, which has many benefits for both you...
Suspended scaffolds are of three types—fixed, operated by pulleys and operated bywinches. (Provision for stability should be provided for these when using them in places subjected to heavy wind forces). (i) Fixed type suspended scaffolds. ...

@SkittisH - That's a really good point. I hadn't thought of the fact that pulleys are still used in elevators. In fact that's probably the place I've seen them most often (in movies at least, when a character is leaping around on top of the elevator). ...
