Part A) Simple units conversion- 2400 revolutions per minute\n1 revolution= 2 pi radians\n1 minute = 60 seconds\n2400 revolutions per minute * 2 pi = radians per minute\nTake that number and divide by 60 to get radians per second\n(Answer  251.327 rads per sec)\n\nPart B) \nFirst lets find out the circumference of the tire-\ncircum= 2* pi * r (simple geometry also pi*diameter)\ncircum= 251.327 cm = 2.513 meters (odd coincidence- i think not)\nOk now lets see how many revolutions in makes in 1 hour\n100 km/h = 100,000 meters per hour\n100,000 meters per hour  / 2.513 meters per revolution = 39793 revolutions per hour\n663.21 revolutions per minute (simply divide by 60 for minutes then again for seconds)\n11.05 revolutions per second (thats really fast)\n69.45 rads per second (multiplied the previous number by 2 pi)

A separate device, based on something like a drilling power tool, is used to spin a special axle in the rear of the car, which is connected to the gearbox and to the engine; spinning it at a certain speed spins the axles at that same speed and kick-starts the engine. There is no such thing like an ignition key.

F1 gearboxes are semi-automatic 7+1 speed gearboxes controlled by paddle shifters. That's 7-speed for forward motion and a reverse gear. But its use is restricted by the rules to certain situations and to certain parts of the track.\nA car is disqualified if it moves in the pits in reverse gear.

Tachymeters measure speed. You time how long it took you to run a certain distance or do some given task and that is how fast you did it.

Torque wrench\nFrom Wikipedia, the free encyclopedia\n\nA torque wrench is a wrench used to precisely set the torque of a fastening such as a nut or bolt. It is usually in the form of a socket wrench with special internal mechanisms. A torque wrench is used where the tightness of screws and bolts is crucial. It allows the operator to measure the torque applied to the bolt so it can be matched to the specifications. This permits proper tension and loading of all parts. A torque wrench indirectly measures bolt tension. The technique suffers from inaccuracy due to inconsistent friction between the fastener and its mating hole. Measuring bolt tension (bolt stretch) is more accurate but most often torque is the only means of measurement possible.\n\nBeam type\n \nBeam type torque wrench. The indicator bar remains straight while the main shaft bends proportionally to the pressure applied at the handle.The simplest form of torque wrench consists of a long lever arm between the handle and the wrench head, made of a material which will bend elastically a little under the applied torque. A second smaller bar carrying an indicator is connected back from the head in parallel to the lever arm. This second arm is under no strain at all, and remains straight. A calibrated scale is fitted to the handle, and the bending of the main lever causes the scale to move under the indicator. When the desired indicated torque is reached, the operator stops applying force. This type of wrench is simple but not very precise.\n\n \nClose up of beam type torque wrench showing detail of the torque display scale. This shows a torque of about 160 inch pounds or 17 newton meters.\n\n\nClick type\n \nClick-type torque wrench, adjusted by turning the knurled handleA more sophisticated method of presetting torque is using a calibrated clutch mechanism. At the point where the desired torque is reached, the clutch slips, preventing overtightening. The most common form uses a ball detent and spring, with the spring preloaded by an adjustable screw thread, calibrated in torque units. The ball detent transmits force until the preset torque is reached, at which point the force exerted by the spring is overcome and the ball "clicks" out of its socket. The advantage of this design is greater precision and a positive action at the set point. A number of variations of this design exist for different applications and different torque ranges.\n\nCalculation for torque wrench spanners and adapters with a dial wrench\n\nWhen using extension adapters and spanners, the torque applied to the nut is greater than that shown on the torque wrench dial. To calculate the increase, use the following formula:\n \nTT = DR (L+E)\n     -------\n        L   \n\nTT = True Torque\nDR = Dial Reading\nE = Extension Length\nL = Effective Wrench Length

A tachymeter (also tachymetre or tacheometer) is a kind of theodolite used for rapid measurements and determines, electronically or electro-optically, the distance to target, and is highly automated in its operations. Tachymeters are often used in surveying.\n\nOn watches\nA tachymeter is also used as the name of a scale sometimes inscribed around the rim of an analog watch. It can be used to compute speed based on travel time. To use it for this purpose, start the chronograph at a mile marker. At the next mile marker, the point on the scale adjacent to the second hand indicates the speed (in miles per hour) of travel between the two. A standard tachymeter will only determine speeds greater than 60 miles per hour using this method; slower speeds can be measured by decreasing the unit of measurement (to half-miles or kilometers, for example).\n\nThe speed of an object is defined by the equation\nSpeed = Distance/Time\n \nThe tachymeter scale computes the function\nTachymeterDial = 3600/Elapsed Time\n. \nThe spacings between the marks on the tachymeter dial are therefore proportional to 1/t where t is the elapsed time, but because of the somewhat similar pattern and because of people's familiarity with logarithmic graph paper, the tachymeter scale is sometimes also mistakenly described as logarithmic.\n\nThe function performed by a tachymeter is independent of unit of distance (i.e. is not specific to miles or kilometers). A tachymeter can be used to measure speed in nautical miles per hour or meters per hour, or to measure an industrial production process in units per hour. A tachymeter is simply a means of converting elapsed time in seconds per X to X per hour.\n\nThe scale is generally only accurate for elapsed times over approximately 7 seconds.

with some grinds of camshafts you may sacrifice rpm for torque/you have to put together the right package for what you want to use the vehicle for

That is a great question!  I grew up in New Zealand where manual (standard) transmission is the norm.  Now that I live in the USA, it is the other way around.  Automatic transmission is the norm here.  As I prefer shifting gears myself my first vehicle here was a Toyota Celica GT Convertible and I loved that car...it comes as a manual (standard).  Unfortunately they stopped making them. :(\nSo I have compromised with a new Toyota Solara SLE Convertible with tiptronic transmission...which gives me the ability to switch from Automatic to Manual and is fast changing as no clutch needed.  Great for overtaking :D\nNow Toyota are releasing a hybrid vehicle that will look great, perform well and give you almost 80 miles per gallon.\nAll they need to do next is add wings so we won't need to use roads anymore (smile).

they are pre-calibrated with reference to the circumfrance measure of the tyre. each rotation of the tyre is counted as the distance travelled and analog metre shows the speed which is corelated to the wheel by a rotating gear. It is funny to watch the speedometre showing the speed when the vehcile is parked but lifted on jacks and if one rotates the front tyre even by hand.

it's like the speedometer of a vehicle. the higher the reading the faster it is...

combustion? your question i super vague. the drive shaft applying torque created by the engine to the wheels which turn making the car move? you might want to be more specific. and if you look at wikipedia.org under combustion engine you might find what your looking for

i go with a four-wheel drive car like ford 500, i like abs and traction control as well as keyless entry. but i also like the new design on honda civic. also the lamborghini murceaulago-zOOOOOM!
