Here we have loads acting offset by some kind of lever arms on the beam.
00:08
And so what happens here is that we can draw free by diagrams of those bending arms, and we can see that we get the resultant force and a result in moment acting where they attach to the beam.
00:23
So the moments we can figure out from the kind of the length of the bending arm, which is 200 millimeters.
00:30
So we have an applied load at f .a and one at fb reaction, i mean reaction loads.
00:40
And we can see that it turns out that this one is actually going to be, well, this will be up.
00:52
But then we also have the load from the applied load acting at b in the moment here.
01:01
So if we go through and make our cuts, you can see here, and we go, well, first we can, again, we can just do a free -by, bending, i mean, a force and moment balance on this guy to figure out that this is 180 and this is 60.
01:19
And so we make our cuts here, and we can see that this sheer force is 180 newtons in this region, and that's where it's a maximum...
