Okay, so to draw a free body diagram for this bent object, we need to look at all the forces that are acting on the object.
00:10
And so the first one and the most obvious one is the p force, which is pointed straight down.
00:17
And so we'll draw that straight down like this as our force p.
00:22
But then there's also a downward force due to the weight of the object.
00:27
So let's draw that in green.
00:29
So that green force there, that's f sub g, that is the weight force.
00:34
And then there will be a tension force that will be at an angle like this.
00:38
That's our tension force due to the cable here.
00:41
And then there will be an upward force due to the normal force on the floor.
00:48
Now normal forces are always perpendicular to the surface...
