I know what its called. What causes it?

It's called the Lorentz-Fitzgerald Contraction.

I am not sure whether the question is "to appear to undergo length contraction" or "to actually undergo length contraction"? An object doesn't actually undergo length contraction if you are in the same frame of reference as the object. It is only when you are in a different frame of reference to the object that it APPEARS to undergo length contraction, since you are using a measuring instrument which is travelling near to the speed of light RELATIVE to the object. It is all a trick of the light!!

according to the relation m=M/(1-(v/c)^2)^0.5
when v approaches c [speed of light] m approaches infinity.
so the body tends to collapse under its weight and all the molecules will try to align themselves along the axis of the body.
so literally the body contracts

Basically it is resistance of the space-time continum. If you reach the speed of light your mass would become infinite and so would your resistance.
