Wind resistance goes up with the square of speed. Means that if you double the speed from say 30 to 60 you will have 4 times the wind resistance. It is mainly wind resistance that eats fuel on level ground. The faster you want to go the more power it takes to do it. That is is why you just can't change the gears in some vehicle and break the land speed record, that takes power, not just gears, power to pull the gears is required. I admit that some engines and gear combinations may be better suited to slightly different speeds, but in general the faster you want to go the more power/fuel you need. Try an expirment. Get on a bicycle and see how fast you can go. Why can't you go faster? You need more power to overcome the wind resistance, if this wasn't the case you could just shift into a higher gear and keep on going faster and faster. But a good bike rider has a tough time averageing more than 20 for long unless he is in a group to draft with. You just can't pull a higher gear without more power, and the faster you go the more power it takes. Facts.

It’s amazing how a little floor jack can lift tons and tons of weight with just the flick of a handle. What’s even more amazing is that all the principals of hydraulic theory can be wrapped up in such a small package. This same package applies to any hydraulic system from the largest bulldozer to the oldest and smallest tractor. This short series will take a look at the basic layout of a simple hydraul
