The soundtrack was also processed with volume normalization, noise reduction, clipping reduction, and equalization (the resulting sound, though not perfect, is far less noisy than the original). http://en.wikipedia.org/wiki/Transmission_(mechanics) A machine consists of a power source and a power transmission system, which provides controlled application of the power. Merriam-Webster defines transmission as: an assembly of parts including the speed-changing gears and the propeller shaft by which the power is transmitted from an engine to a live axle. Often transmission refers simply to the gearbox that uses gears and gear trains to provide speed and torque conversions from a rotating power source to another device... Manual Manual transmission come in two basic types: - a simple but rugged sliding-mesh or unsynchronized / non-synchronous system, where straight-cut spur gear sets are spinning freely, and must be synchronized by the operator matching engine revs to road speed, to avoid noisy and damaging "gear clash", - and the now common constant-mesh gearboxes which can include non-synchronised, or synchronized / synchromesh systems, where typically diagonal cut helical (or sometimes either straight-cut, or double-helical) gear sets are constantly "meshed" together, and a dog clutch is used for changing gears. On synchromesh boxes, friction cones or "synchro-rings" are used in addition to the dog clutch to closely match the rotational speeds of the two sides of the (declutched) transmission before making a full mechanical engagement...

What's the difference between all-wheel drive and 4-wheel drive? 4WD is not on all the time, under normal conditions, only the rear wheels drive the vehicle forward, while the front wheels spin freely. To activate a modern four-wheel drive system, the driver has to push a button or pull a lever to engage it. But four-wheel drive isn't meant to be on all the time so you have to know when to turn it on and when to turn it off. AWD is on all the time, and mostly used in cars, and the computer manages the system. Just going down the highway, the system will send most of the power to the rear wheels, for maximum fuel efficiency, if the road condition changes, such as rain or snow, the system adapts and evenly distributes the power evenly to all 4 wheels, so you have maximum drive grip, with little to no chance of wheel spin. 2WD Cars are less complex than those with AWD or 4WD, and their simpler drivetrains mean improved fuel economy in the long run. In general, cars equipped with 2-wheel drive get better gas mileage than models that use all-wheel drive or 4-wheel drive.

Top things you didn’t know the purpose of! These are the everyday items and things you didn’t know the use for! #14. “Pen Cap”-- You have definitely noticed the tiny hole in the top of a cap and may have used it to try and make a whistle or pretended it was a tiny spyglass. Most people believe this hole has something to do with preventing a pen from drying-out but this is not the case. The hole in the pen cap actually serves as a safety feature. In the event that a small child swallows one, the hole allows air to pass through and reduces the risk of suffocation. #13. “Measuring Tape Tools”-- The modern measuring tape machine is a handy invention that most construction workers and contractors can’t live without, but even some of the most skilled workers might not know it has two incredible yet simple features. First there is the serrated edge on the metal end of the tape. This was put into the design so that if you desired you could put a minor scratch or indentation into the surface you are measuring, in order to give you a marker to make further measurements or designs off of. The other feature is right next to the serrated edge. You may have noticed the small hole that is commonly located in the metal tip. So what’s the purpose of this? Well this is so that if you are measuring something from a point where a nail or screw is you can hook the tape onto the nail and hold the tape in place. #12. “The Quarter’s Edge”-- You probably have spied the hundreds of tiny grooves that mark the outside edge of a quarter but not thought twice about it having a purpose. But these tiny ridges actually once served an important function and no it’s not just so magician’s can get a better grip during coin tricks. Up until recently, historically speaking, the cost of the metals in a coin reflected the coins value so many people took to shaving the edges off of the coins and then used the rest of the coin to purchase items as if the coin still had full value. They would then save up their shavings and melted them together to create new coins or just sell the chunks. In order to combat this, coin minters started putting these ridges on their coins so that retailers could tell whether the coins had been shaved. This practice, though not necessary today, is carried on for the sake of tradition and aesthetic. So why don’t nickels have them? Because no one cares about nickels.
