Not all tracks run counter clockwise. Barbagallo Raceway in Perth Western Australia runs clockwise. Aswell as Queensland Raceway in Australia. Silverstone runs clockwise. Brands Hatch runs clockwise. There just a few. Want to know more just ask.

ill make it uber simple for you! \n\nthink of the CPU as a train station \n\nthe Pentium 4 has 1 train track coming in and two coming out\n\nso it can only service one train at a time \n\nthe Pentium 4 HT's have two rails coming in and two coming out  so now they can service two trains but it still can only use the same amount of people as the regular Pentiums to get the train loaded or unloaded\n\nnow the Pentium 4 DC's have two tracks coming in and two tracks coming out with two work crews to service each train. \n\n\nnow in geek talk\n\nthe Pentium 4 ht benefits over the regular Pentium cpus by using a advanced l2 cache and supplements that with another l3 caches that service a 2nd data pipe line, while that is effective the Pentium 4 dual cores have two central processors compared to the older single core processors while this is somewhat of a advantage our current north bridges are not effective to supply each core with enough data to process at the moment. so you may be better getting a single core CPU rather then a dual core and waiting on a dual NB or joint NB motherboard\n\n\nBwhahahaha\n\nlmao hope this helped

They conduct power and motion between non-intersecting, parallel axis that may or may not have center groove with each group making two opposite helices. The two helix angle come together in the center of the gear face to form a 'V'. in these gears the end thrust forces cancel themselves out. Its difficult to cut this type of gear but its made easier by machining a groove in the face at the point of the apex of the 'V' creating a break in the middle of the herringbone gear teeth. They do not have any separating groove between the mirrored halves. \n\n Action is equal in force and friction on both gears and all bearings. Herringbone gear also allow for the use of larger diameter shaft for the same volumetric displacement and higher differential pressure capability.\n\nThe most common application is in power transmission. They utilize curved teeth for efficient, high capacity power transmission. This offers reduced pulsation due to which they are highly used for extrusion and polymerization. Herringbone gears are mostly used on heavy machinery.\nIN PUMPS:\nherringbone gears will reduce shaft loads and produce a very quiet running pump.\n      Herringbone gears are actually double helical gears with teeth angles reversed on opposite sides. This causes the thrust produced by one side to be counterbalanced by the thrust produced by the other side. The two sets of teeth are often separated at the center by a narrow gap for better alignment and to prevent oil from being trapped at the apex. \n\n      Herringbone gears are best suited for quiet, high-speed, low-thrust applications where heavy loads are applied. Large turbines and generators frequently use herringbone gears because of their durability.

Technically your bike has 21 gears--the number of rings on the front times the number of rings on your cassette in the back.  However, you don't really have 21 usable different gears.  This is because:\n\n1) Depending on how many teeth are on your chainrings (front rings, you have 3) and your cassette (7 rings on back), you may have some gears that repeat.  It is all about the ratio between the front ring and the back ring the chain is on.  For example, let's say your middle front ring has 38 teeth and one of the rings on your cassette in the back has 19 teeth, you have a ratio of 2 to 1 when your chain is on these two rings.  If your smallest ring in the front is 28 teeth and your smallest ring in the back is 14, you again have a ratio of 2 to 1, so these gears are actually the same.  \n\n2) There are also certain gears you should not use.  You should avoid cross-chaining--being in smallest ring in front (closest to the bike, on the inside) and the smallest ring in back (farthest away from the bike) or largest in front (farthest away from bike) and largest in back (closest to the bike).  Either of these gears, or close to them, puts a lot of stress on your chain because it torques it sideways.  This will cause additional wear on the chain and shorten the life of it.  Most bikes will allow you to do this because the chain is put at a length to allow for it, but it will also likely cause your chain to rub somewhere and also possibly make your bike not stay in gear very well.  \n\nHowever, these days, rather than multiplying the number of front and back rings to get speeds, bikes are now often referred to by the number of rings on the chain ring and cassette separately.  You ride a 3 by 7 (3x7).  A double road bike with a 10 speed cassette (typical of today's high end road bike) is a 2x10.  A more touring oriented road bike often has a triple chainring and is likely to be a 3x9 or 3x10.  A fairly typical mountain bike is a 3x9, but there are a lot of 2x9 or 3x8s out there too.

Gears that are designed with either a known end force or to combat a known end play condition due to loading and unloading, usualy in low rpm applications

you can get gears to handle some change in the plane (I think they are called hypoid gears)

We make small display rotators if you check out our web site you can get an idea how we build them. You probably just need a slower gear motor. You can change the pulleys for different speeds but then you need to change the belt size. It is always easier to get a motor close to the final speed you want.\n I don't know what the cabinet looks like or what kind of space you have for the motor but it may help to see how we build them. www.semcomotion.com

The first reasonably accurate mechanical clocks measured time with weighted pendulums, which are useless at sea or in watches. The invention of a spring mechanism was crucial for portable clocks. In Tudor England, the development of "pocket-clockes" was enabled through the development of reliable springs and escapement mechanisms, which allowed clockmakers to compress a timekeeping device into a small, portable compartment. In 1524, Peter Henlein created the first pocket watch. It is rumoured that Henry VIII (the portrait of Henry VIII at this link shows the medallion thought to be the back of his watch) had a pocket clock which he kept on a chain around his neck. However, these watches only had an hour hand - a minute hand would have been useless considering the inaccuracy of the watch mechanism. Eventually, miniaturization of these spring-based designs allowed for accurate portable timepieces which worked well even at sea. Aaron Lufkin Dennison founded Waltham Watch Company in 1850, which was the pioneer of the industrial manufacturing by interchangeable parts, the American System of Watch Manufacturing.

You have a bevel gear on the end of the drive shaft (the input shaft to the differential). This gear right-angle drives a large "planetary" or ring gear that rotates about the axle but is not attached to it directly, but is attached via a yoke that carries two intermediate bevel gears, and these gears mesh with the gears that drive the two wheels. (You really need to look at the ref.) When the two wheels want to rotate at the same speed, the two bevel gears do not need to rotate and the transmission acts like a simple nondifferential mechanism. However any differential motion of the wheels is accommodated by rotation of the intermediate gears.\nP.S. For some reason I had to go to another page (at the ref. website) and then back to get the animations to work right.

the device is called a phase sequence indicator.  you connect it to the leads of the motor and rotate it and it will tell you the sequencing of the phases

Before you can answer this you need at lease to variables. You have the voltage of 1.5 vdc. You will need Amp the clock pulls. Wattage = Volts X Amps.

Synchro motors are usually operated in pairs (that remain synchronized!).  For example a synchro motor may be rotated many degrees when the wheel on the bridge is repositioned to steer a large ship.  A second synchro motor in the steering gear room connected to the first motor senses an imbalance in its electric circuitry and rotates the same amount to duplicat movement of the wheel.  The second synchro is then used to control the steerin gear engine controls until the rudder is repositioned as desired by the bridge.

I know it has at least 4. You can probably find the definitive number in one of the links below.
