Artwork: How pulleys work#2: With two wheels, it's as though the weight is hanging from two ropes (the two strands of the same rope on the left), and a pulley halves the lifting force you need. It's like lifting the weight with two ropes instead of one. But you now have to pul...

Answer to: Explain how a correctly installed and operated ball-bearing assembly, using clean and appropriate lubricant, may still fail by metal...
Pulley – a grooved wheel with rope running along groove. Changes amount and/or direction of force applied. By arranging pulleys in such a way as to increase distance that effort force moves relative to distance weight moves, a pulley can reduce effort force needed. ...
And once you are guiding, you are limited by centroid accuracy and response and - well - you are guiding anyway - so what is the benefit of encoders vs. tight guiding. It may mean "less work" for the guider - but who cares how much the guider works if the resulting fwhm is small...
In science, tools like this are called simple machines. And although you might think there's a big difference between a tiny little wrench and a huge great earthmover, exactly the same physics is at work in both. Let's take a closer look at tools and machines and how they work!
How does it work? The driving motor (green, right) powers the load (orange, left) through an axle (yellow) and pulley system (gray). As the speed of the axle changes, a centrifugal governor (dark blue) and electric circuit (top right) switch a small electric motor (pink) on or off...
Question: Explain whether or not a mechanical advantage of a simple machine can be less than 1. Mechanical Advantage: Mechanical advantage is used to define the mechanical efficiency of a simple machine. It is basically the ratio of movement of resistance force and the applied...
