Imagine a disk spinning at near light-speed; the outside is spinning faster than the inside; what would be...?

Question

...the effects of relativity and time dialation on the disk?

Answer 1

It would be similar to an accretion disc. A solid disc would probably be torn apart by the differential forces involved.
This type of thing would be similar to a neutron star revolving 2000 times a second. With a diameter of 10 miles, and a circumference of 31.4 miles the surface would move at 62,800 miles/sec
The center, only 5 miles away would be rotating, but would be relatively standing still.
Interesting concept.
The time dilation and mass increase only happens much closer to the speed of light.
I once calculated, because of a story by Larry Niven concerning travel with a bussart (sp?) ram jet, that after accelerating halfway to the Andromeda Galaxy at 1 G, the speed reached would be .3 mm/sec short of the speed of light, and at that point the time dilation and mass increase would be 770,000:1

Answer 2

There are 2 forms of pace, so you are each proper to your possess methods. The so much usual variant of pace is measured in meters consistent with moment (or miles consistent with hour). The outer dot will probably be journeying extra meters within the identical quantity of seconds, so it's going to have a better pace. The different sort of pace this is referred to as angular speed, and it may be measured in levels consistent with moment. Both dots can have the identical angular speed, when you consider that they are going to each whole a 360 measure rotation within the identical quantity of seconds. Angular speed is similar to RPM, for illustration a 33 RPM list.

Answer 3

It would follow the rules; the outside edge would increase in mass. Time would pass slower on the outside, causing the disc to wind up in a spiral.

The disc would probably shatter, even if it was made of neutronium.

Answer 4

some dude is right. he knows his stuff, yea go some dude

Answer 5

It will get smaller

Answer 6

why would you wanna know that????
