Orville and Wilbur Wright owned a bicycle shop in Dayton,Ohio.Although they had not gone to school to learn about airplanes or engineering,they were good mechanics.By repairing bicycles,they had learned how gears and pulleys worked.They also learned to take careful notes about ...
Pulleys are examples of what scientists callsimple machines. That doesn't mean they're packed withenginesandgears; it just means they help us multiply forces. If you want to lift a really heavy weight, there's only so much force your muscles can supply, even if you are the world's stro...
As it turns out, the automated stitching mechanism at the heart of a sewing machine is incredibly simple, though the machinery that drives it is fairly elaborate, relying on an assembly of gears, pulleys and motors to function properly. When you get down to it, the sewing machine is among...

Levers and pulleys are uncomplicated machines that make work easier by improving mechanical advantage, meaning that they reduce the effort needed to do a task. They provide "leverage," changing the direction of our effort.
The transformer gears this high speed (high speed, low torque=high voltage, low current) down for much less speed (less voltage swing) but much more torque (current).The alternating current audio signal flows through the speaker's voice coil which generates a magnetic field. The voice coil ...
The same can be said of circular mating parts like sprockets and gears. In this case, the "free with service" slop of laser cutters is beneficial - gears, pulleys, and sprockets that are too small will just act like worn out regular ones. But the waterjet taper will absolutely kill your...
CVTs also have various microprocessors and sensors, but the three components described above are the key elements that enable the technology to work. HowStuffWorks The variable-diameter pulleys are the heart of a CVT. Each pulley is made of two 20-degree cones facing each other. A belt rides...
The projects include: incline planes, levers, wheels and axles, gears (spur, compound, rack and pinion, and planetary), cams, cranks, pulleys, ratchets, and springs. Hands-on, interactive, and engaging, this kit will bring out the DIY and inventor spirit in every child.Nick ...
