In this problem we have a kind of a frame here and it's got some external load acting at some various places on it.
00:10
It has a roller support on the right end and is pinned on the left end.
00:16
So again, i'm going to write force vectors.
00:19
And so the force of f1 is in the horizontal direction of 5 kilnibals.
00:24
Its position vector is 2 in the horizontal and 2 in the vertical meters.
00:30
And then the, let's see here, f2 is the pin here, and i'm going to call that the origin.
00:43
F3 is this roller support, and it is at a position six meters to the right of the origin.
00:54
And then f4 is this load here, and it is minus six in the vertical direction...
