Determine the angular velocity of links a -b and link b -c at the instance shown.
00:08
Okay, so now let's try to use our kennedy theorem.
00:15
From our kennedy theorem, we could write down our values i -3 and i -4.
00:25
So let's draw our bar again.
00:28
If we draw our bar in this way, sort of like a triangle, then this is i13, here's our bar c, at i23, and this is i12, i14, and i3, and i34 at point b.
00:46
By our kennedy theorem, we have v of i23 equal to omega 3 times i23 times i13.
00:58
Omega 2 is just our 4 radiance per second.

B .c.
01:05
Is 60 centimeters, and c .d.
01:08
Is 50 centimeters...
