Mechanical devices can change one form of force ... This difference in speed is called the gear ratio. The driven gear has 60 teeth and the drive gear has 15 teeth. Gear ratio = 60 ÷ 15 = 4 ...

In thinking about how so many of the recent events Machine Design has covered have focused on artificial intelligence, I ...

However, the two gears can vary in size to achieve a different gear ratio. An example of this is in a hand drill, where the drive gear is larger than the driven gear. A pillar drill with a rack ...

and follows a decimal design in which the rotation of a gear with ten teeth represents the numbers 0 to 9. We’re taken through the mechanical processes behind addition, subtraction ...
