As per the question, we are given with the polygon.
00:04
We can draw, right? this is point a, which is fixed.
00:12
This is point e.
00:15
This is point c.
00:16
This is point b, which is also fixed.
00:20
Right? so, a and b are fixed here.
00:23
And this angle is given to us as 60 degree.
00:27
What are the values given? a .b.
00:30
Is equal to c .e.
00:31
Is equal to 150 millimeter which is given bc is equal to 40 millimeter right ea is equal to 80 millimeter these are given and n of bc is equal to 120 rpm which is equal to n of c so from here we can find omega c first this will be 2 pi n divided by 60 so we can solve 2 pi multiply by 120 divided by 60.
01:04
So it is 12 .56 radian per second.
01:09
As this will be cancelled, this is 4 pi.
01:12
Right.
01:13
So we can find vc, which is equal to rc omega -c.
01:17
So we can convert rc.
01:19
This is equal to 0 .04 meter.
01:23
Right? so which is equal to rc.
01:26
So this is 0 .04 multiplied by 12 .56.
01:31
We will get 0 .5024, right? this is meter per second.
01:38
This is velocity.
01:39
Now we know that velocity diagram we can draw for above figure...
