We are given a dose of mass equal to 10 kg, rotating on the horizontal axis.
00:09
We can grow the vehicle like this, which is our taste.
00:14
And a string is wrapped around it.
00:17
It is a smaller mass, say m.
00:23
Our game is 3kj.
00:28
The these is radius of separate point in the southern side.
00:36
And the inertia is given by a mass sphere.
00:51
First, we have to find out the weight of the disk.
00:55
So weight of the disc only will be this mass and restoration to be that is 10.
01:04
Our g is 9 .8, that is 98 neutroids.
01:13
So this is the weight of our disk penalty.
01:16
In the second question, we have to find out the expression of the small mass m.
01:24
For this, we'll see that in the small mass small m, the acceleration will gravity adds downward.
01:32
So the weight will be mg and the tensor on the string will be d.
01:38
So we can write ng minus t would be m, a.
01:50
If our acceleration is related to round words or we can write t would be equal to m g minus m m m s say it is an equation 1 now we know the tau is i into alpha that implies in our case tau will be forced into particular distance that is tensed t and in the perpendicular distance is our r so t into r equal to i is given by m r squared by two...
