does anyone have a formal defintion of what gears with lateral offset means?

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

Look at flexions at the point of supprt:\n1 is the support solid so its flexure can be ignored\n2 is the steel rod held by a grub screw. If it extends any distance to lock the rod then some rotation will occur due to it bending\n3 if held in a chuck check slippage.\n\nIn motor cars torque transmission is usually accomplished using splined shafts, but for small oscillations the backlish in these will be large.

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.

Round-off Double back-handspring double back layout. \nJust Joking.\n\nRound-off Double back-handspring!!!!!!!!\n(not joking)

no, gears can vary it depennds on the diameter of the gears ,a small gear turns faster

The left hand lever will contol the gear shifter on the chainring (at the front) and the right one will control the shifter on the sprockets (at the back).  \n\nPulling either lever back will move the chain to a larger chainring or sprocket.  At the back a larger sprocket means a lower gear (pedalling is easier but you have to pedal faster) and at the front a larger chainring will mean a higher gear.  An "older" bike will probably have 2 chainrings on the front and 5,6 or 7 sprockets on the back.  This means that you will be making most of your gearshifts using the right hand lever, forwards for higher gears and backwards for lower.  Think of your left hand lever as a "low range" or "high range" selector, you pull it back for higher gears when you are going fast and push it forwards for lower gears when you are going slower, climbing hills.\n\nIt is a common problem to lose the chain when you move from the small chainring to the large.  This means that your shifter is moving a bit too far, pushing the chain off.  To stop this from happening you need to set the limit stops on your shifter mechanism.  Your front shifter will have 2 small screws attached to it, if you move the left hand gear lever you will see that these screws limit the movement of the shifter cage.  Find which screw stops the movement of the shifter when you pull the lever back and tighten this one by about a half turn.  If you are losing the chain off the small ring then you need to make a similar adjustment to the other screw.  If you then find that you can't shift the chain between the rings hen you have over adjusted and you need to loosen the appropriate screw a little.\n\nIf you are having problems withthe chain at the back the rear mechanism has a similar arrangenet of 2 limit stop screws and the same principle applies.

They are called lateral moraines.

it should be the pedal on the far left...leave your foot on it to switch gears and release when not needed.

The power transmission system in a bi-cycle is of chain type. The mechanism is as follows. The larger driving sprocket is driven by the motion of pedals. The roller-bush type chain connecting the driving sprocket and the smaller driven sprocket transmits power from pedal to the rear wheel. Due to the smaller size of the driven sprocket, the speed multiplication occurs ( the speed of rotation of rear wheel is larger than speed of rotating the paddle).\n\n[You may also note: A chain, like a power transmission belt, has a taut and a slack side. In usual conditions i.e. while going forward, the slack side is at the bottom and taut side at the top. If the direction of rotation of pedal is reversed, the top side of the chain becomes slack and bottom side is taut.]\n\nLet us come to the specific topic now.  While doing reverse paddle, the chain tends to drive the driven sprocket in opposite direction. The smaller sprocket is provided with "ratchet-shaped" teeth. So the chain and driven sprocket doesn't mesh but slips. Thus preventing any power transmission to the rear wheel. Thus there is no motion of rear wheel and hence the cycle cannot be driven backwards.\n\nLearn about ratchet from

Having left side drive will only help if you grind on your right side. If you grind on the right side and have right side drive you are more likely to hit your chain and sprocket if you mess up while grinding. Other than that it doesnt have any other advantages than right side drive.

I think you mean ganged.  This just means connected together mechanically, like a ganged switch.  I'd guess they're variable capacitors (e.g., tuning capacitors) all on the same shaft.  Ganged could mean electrically connected together, but that's a more colloquial use of the word.

It is a horizontal belt which is mechanically driven in a continuous loop.  Items are laid on it and moved by the belt to eliminate manually carrying them.

Gear ratio, or in a car, final drive ratio is basically the number of times the tires rotate in relation to the number of times the drive shaft or axles rotate.\nLet's say in a rear wheel drive car you have a rear end gear of 3.91:1 This would sound out as three point nine one to one.\nThe drive shaft will rotate 3.91 times for every 1 complete rotation of the tires.\n\nThe transmission also has gears, and each speed has a ratio, 1st gear, or Low being the lowest ratio. Usually somewhere in the 2.78:1 neighborhood. 2nd, or Low2 would be a bit higher, say 2.02:1 3rd gear, or D would be something like 1:60.1 and 4th or Overdrive would be 1:1 or an equal rotation of 1 to 1.\nOf course these are random numbers, and several things will factor in for actual ratios in a trans, and/or rear end.\nFront wheel drive cars also have a final drive gear, and would be similar in ratio to the rear end ratio of a rear whel drive car or truck.
