It depends on what you need - if you want lots of speed no power on the bottom end you go with the high ratio - if you want lots of torque on take off and lots of pulling power you take the low gear ratio.
Usually a high gear is better in snow because it does not slip as easy.
A high Sortino ratio is better than a low Sortino ratio. That's because a high sortino ratio implies low downside volatility compared to the expected return. There's a guide to the Sortino Ratio at the related link, together with an Excel spreadsheet
High gear ratios, 273,373,340 Low ratios, any thing starting with the #4 and up is a low gear ratio. 410 411 456 488 556 and up.
Not sure when you say low speed. Not knowing what your driveline ratio is I will just use some basic numbers .If 20 MPH is your speed and you were in first gear your engine RPM's would be 3000, if you were in second gear at 20MPH your engine RPM's would be 2500 , if you were in third gear at 20MPH your engine RPM's would be 2000. A difference of 1000 RPM's from low to high gear. Lower engine RPM's less fuel used.
1.96:1 is the low range gear ratio of an np 205.
With the 4.10 you get low end torque. With the 3.08 you get more top end spend.
Signal to noise ratio is the difference between the noise floor and the reference level.
The rear end gear ratio on a 1980 Oldsmobile is 3.73, in the overdrive gear. The low gear ratio is 1.43.
That would depend on the gear ratio between the engine and the wheels, and in the diameter of the wheels. The transmission of the car lets you change the gear ratio, so in low gear the car may be going 15 MPH, while in high gear the car may be going at 70 MPH.
A double over bicycle will have two gears for the chain and it allows for easier pedaling up and down hills. When you are in a low gear, you will find that having the chain on the smaller gear will work better than having it on the large gear, which should be reserved for the high gear.
In motor-driven vehicles it's often best to use a high gear, as it reduces the likelihood of the wheels spinning loose. For a bicycle it's often better to use a low gear, as it makes it easier for the rider to control the power.
Nothing really. But remember that the front and rear ring and pinion MUST be the same gear ratio. You didn't say if the Z71 was a 4-wheel drive. If it is not then you will either kill the engine power are may even increase the power.That depends on the gear ratio in the 3/4 TON rear end and the 1/2 ton rear end. / DIFFERENCE Low gear verses high gear. Low gear= Power. High Gear = No power.
