the circular profile at the bottom becomes elongated with wear, and "hooking" occurs at the top

What are the causes of bike chain slip?
Usually what happens is that the chain elongates under wear, which forces the rollers farther apart. Depending on set-up this can then cause the chain to ride higher up on the teeth of the sprocket, eventually to the point where it can jump over the top of the teeth. On other set-ups the elongated chain will wear out the flanks of the teeth to the point where their angle can no longer retain the chain.
If you wear a retainer to correct the alignment of your teeth will the shape of your jaw change permanently?
no, if you stop wearing the retainer the teeth will move back, your jaw bone dosent change!
Your 21 speed mountain bike chain keeps slipping under a load mostly up hills?
Usually what happens is that the chain elongates under wear, which forces the rollers farther apart.

On other set-ups the elongated chain will wear out the flanks of the teeth to the point where their angle can no longer retain the chain. Your best bet of fixing it is to have both the chain and the freewheel replaced. Chain and the rear sprocket pack wear together, replacing only one of them often don't fix the problem. If it's really bad you might also have th replace the chainwheel(s), the sprocket(s) up by the pedals.
How does a chain and sprocket work?
To see how a chain in sprocket works in action, you can turn a bicycle upside down and turn the pedals.But here are the particulars:A sprocket is a type of gear, or "Cog-Wheel". Its teeth slot into the gaps in a chain, hence gripping it. The chain then essentially becomes an extension of the circumference of the sprocket. This circumference can be made to form irregular shapes such as an oval. It can even be serpentine if redirected by additional sprockets or guides (maybe shaped like the letter S for example). The chain on your bicycle is actuated (moved) by the forward Sprocket, which is known as a Pinion. Your legs power the pedals, which turn the pinion. The teeth on the Pinion grip the chain and the chain rotates about it, transferring the movement energy of the pinion to that of the Sprocket (the gear/s on the back wheel). If the Pinion is small in comparison to the sprocket you will have to pedal faster and you will travel slower. The effort to move the pedals, however, is reduced. If the Pinion is comparitively large to the Sprocket then you will pedal slower and travel faster. Additionally the effort required to move the pedals will increase. The size ratio of Pinion to sprocket is altered by a system of gears. On a bicycle this is usually some kind of derailer, which displaces the chain from one sprocket, forcing it to catch on another. On bicycles with more than 7 gears there is normally a similar derailer to move the chain at the Pinion end. Both a chain and its driving gears are prone to wear over time. This is due to the frictional forces acting between the two. Such a systems' life span can be extended by regular lubrication. The correct chain tension is also important to minimise wear. Sometimes it is sufficient to simply remove a Sprocket and turn it round, as the teeth tend to wear more on the "pulling" side than on the "pushing" side. It should be noted, however that eventually both components will require replacement.
What happens when you don't where your retainer?
Your teeth move, i wear a retainer and if i dont wear it every night my teeth will move, You will GET SPACES. wear your retainer everyday and night to have the best result.

Can you change cloths in the movie in Movie Star Planet?
To change clothes, click on your character. That will open up your mini profile. Once open, look for the button that says, "change clothes". Click on it. You will, then be able to choose which clothes you want to wear out of your wardrobe. To take off the clothes you don't want to wear, click on them. Once you are happy with your outfit, click OK. It will then change your clothes. :) ~orca2love~
