A gear-reduction ratio is calculated directly from the number of teeth on each gear. The number of teeth is a simple value to obtain and that is all you need to complete this computation. After you calculate this ratio, you can use it for any other computation you -- need such as spee...
How to Calculate the Driving Force You can use the ideal mechanical advantage of a wedge to calculate the force on the tip of a wedge (FT) if you know the force applied to the wedge (FA). The relationship is: FT= (IMA) × FA= D/W × FA This relationship is incomplete, however, ...
The best way to compare chainring and cassette combinations between bikes is to check their gear inches. They’re very easy to calculate: it’s the diameter of the wheel, times the size of the front chainring, divided by the size of the rear cog. With this information, you can compare ...
Knowing your rear end’s gear ratio is crucial when you are considering a transmission upgrade, needing to calibrate the speedometer gear in your transmission, selecting the proper gear sets in a transmission, or even getting professional help with a new axle ratio for your application. There are...
In this tutorial the instructor shows how to find the area of an oblique triangle using different formulas. To find the area of an oblique triangle there are different formulae. The first formula to calculate the area of a triangle is area A = (1/2) * a * b * Sin(C), where a an...
Propeller pitch determinesthe final gear ratio between the engine and the water. A boat should be "propped" to operate within its wide-open throttle (WOT), which can be found in the motor specifications or the owner's manual. Read Next: Boat Propellers: Repairs & Replacements ...
It is often said that there are three methods or ways to calculate aircarft weight and balance, but that’s not entirely true. All of these “methods” are based on calculating the weight and balance with a simple math formula. A better way of saying it is that your POH or AFM will ...
‘typical’ fit male. Assuming the same touring bike, gear and body weight, this cyclist could expect to comfortably ride up a 7.5% road gradient. This would drop to a 6% maximum gradient for someone with a lower fitness level. You can find my tutorial on how to calculate the steepest ...
Planetary Gearsets & Gear Ratios Details on Involute Gear Profiles Gear Basics 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 sma...
It’s also important to use the right numbers to calculate the cost of goods sold. Be careful not to include any expenses that aren’t directly related to the sale of merchandise, such as shipping costs or sales taxes. Finally, remember that the inventory turnover ratio is just onewarehouse...
