How are LEGO gear ratios calculated?
To determine the ratio of which two meshed gears will move relative to each other, divide the number of teeth on the driven gear by the number of teeth on the drive gear. This is called the gear ratio. If a driven gear with 24 teeth is meshed with a drive gear with 48 teeth, there is a 1:2 gear ratio.
What gear ratio is best for musky fishing?
The high gear ratio of 6.4:1 allows for quick line pickup when using jerkbaits and soft plastics. The Abu Garcia name has been around for a very long time, and for good reason.
How do I calculate gear ratio?
To calculate the gear ratio: Divide the number of driven gear teeth by the number of drive gear teeth. In our example, it’s 28/21 or 4 : 3. This gear ratio shows that the smaller driver gear must turn 1,3 times to get the larger driven gear to make one complete turn.
How do you calculate the gear ratio in Lego?
For example, you cannot have both more output force and an increase in speed at the same time. To determine the ratio of which two meshed gears will move relative to each other, divide the number of teeth on the driven gear by the number of teeth on the drive gear. This is called the gear ratio.
How to count the teeth in Lego gears?
Relate students’ answers to some of the images from “Images for Classroom Use” or find ideas from the “Overview: Gears” section to stimulate students’ interest.* Find the LEGO® gears shown and count the number of teeth they each have. Start counting from the dot. Build A1 (Direction of rotation).
What does the small middle gear in Lego mean?
The small middle gear is an idler gear. The idler gear does not affect the gear ratio, speed or output force of either the drive or the driven gears. The drive and the driven gears turn in the same direction and at the same speed. This model shows a compound gearing with a 9:1 gear ratio.
How is the ratio of two meshed gears determined?
To determine the ratio of which two meshed gears will move relative to each other, divide the number of teeth on the driven gear by the number of teeth on the drive gear. This is called the gear ratio. If a driven gear with 24 teeth is meshed with a drive gear with 48 teeth, there is a 1:2 gear ratio.
