Hello everybody.
00:02
In rigid body, the relative position between any three points is fixed.
00:07
Now this is called rigid body where the relative position between the three points is fixed, any three.
00:15
Now in case when the rotating they will cover equal angle in equal interval of time.
00:21
Now see this is the rotating axis.
00:25
Now the body is moving in this x along this axis.
00:29
Now what will happen in equal interval of time the points anywhere they will cover equal angle here.
00:36
So omega is fixed because omega is d theta by dt.
00:43
Theta is the angle.
00:45
So change in angle by change in time will be fixed.
00:51
But what happens when tangential speed v is equal to omega into r.
00:56
So this r varies...
