00:01
We'd like to find the max out of balance primary and secondary forces.
00:07
So we're given our speed, n, is equal to 2 ,000 revolutions per minute.
00:16
So omega is equal to 2 pi times 2 ,000 divided by 60, which is 209 .4 radiance per second.
00:25
So that's our omega.
00:26
Our stroke is 120 millimeters, and we also have our crank radius.
00:30
So our cylinder plane position, they're all going to be in the same plane.
00:38
So it looks something like this.
00:41
And our primary crank position, we have 1, 4, 2, and 3.
00:46
So this is 1, 4, 2, and 3.
00:51
So for our part a, we like to find the max out of balance primary and secondary forces...
