You've probably heard of gear ratios, especially when it comes to cars. Thegear ratiois the number of turns the output shaft makes while the input shaft turns one time. If the gear ratio is 2:1, then the smaller gear is turning two times while the larger gear turns just once. It al...
To create large gear ratios, gears are often connected together in gear trains, as shown here: The right-hand (fuchsia) gear in the train is actually made in two parts, as shown. A small gear and a larger gear are connected together, one on top of the other. Gear trains often consist...
Gear ratios are fundamental in understanding how gears work, with the ratio indicating how many times a gear has to turn for another gear to turn once; for instance, in a worm gear, a threaded shaft engaging the teeth on a gear can create a high gear ratio in a compact space. Planetary...
The center of attention is the planetary gearset. About the size of a cantaloupe, this one part creates all of the different gear ratios that the transmission can produce. Everything else in the transmission is there to help the planetary gearset do its thing. This amazing piece of gea...
So when calculatinglightingratios, you measure the light falling on the light or highlight side of the face and compare it to the light falling on the shadow side of the face. For instance, if you have twice as much light falling on the highlight side of your portrait, then the lighting...
However, I’m hoping this introduction to aspect ratios will encourage you to think about them when composing your shot,beforepressing the shutter. It isn’t always ideal tofill the framewith the landscape in front of you. And knowing that the aspect ratio you choose is not dictated by whic...
Understanding aspect ratios helps ensure content displays correctly and helps you choose the right monitor for your needs. The aspect ratio affects everything from how games appear to how efficiently you can work with multiple windows. Pixel Density and Display Quality Pixel density, measured in pixe...
As a result, managers don’t want to give up space or cut back on inventory, even though doing so would free up resources for other opportunities. The fix can be as simple as shifting to ratios (such as sales per squar...
A CVT (continuously variable transmission) is a single-speed transmission that works like an automatic shifter for seamless shifting through a range of gear ratios, unlike other mechanical shifters that offer access to a fixed number of gear ratios. ...
A friction drive is a type of continuously variable transmission, or CVT, in which the variation in gear ratios comes about as a disc connected to the engine (the driving disc) rotates across the face of a second disc connected to the rear wheel (the driven disc). By varying the radius...
