Footwear impression marks { the mark made by the outside surface of the sole of a shoe (the. outsole) { are distinctive patterns often found at crime scenes. They are among the most. commonly found evidence at crime scenes and present more frequently than ngerprints.
Start with a two-gear train. To be able to determine a gear ratio, you must have at least two gears attached to each other â this is called a gear train.. Usually, the first gear is a drive gear attached to the motor shaft and the second is a driven gear attached to the load shaft.. Divide the teeth numbers of the drive and driven gears. The important thing to remember when dealing with gear trains with more than two gears is that only the driver and driven gears (usually the first and last ones) matter. In other words, the idler gears don't affect the gear ratio of the overall train at all.
You can find your gear ratio easily with this method. All you need is a jack, some jackstands, and knowing how to count helps too. You're going to have to put the car in nuetral or out of gear, so safety first! Do this on level ground, and be sure and chock the front wheels so the car can't move.f you have the rearend opened up where you can see the gears, count the teeth on the ring and pinion. Divide the ring teeth number by the pinion teeth number. Example: 41 teeth on the ring and 10 teeth on the pinion = 4.10 gear ratio... Return from Gear Ratio to Drivetrain.
