In this problem on the topic of static equilibrium, we have a brick layer who is 1 .5 meters from one end of a uniform scaffold.
00:08
The brick layer has a weight of 600 newtons, and the scaffold is 7 meters long and weighs 800 newtons.
00:15
There is a pile of bricks that weighs 500 neutrons, 3 meters from the same end of the scaffold.
00:20
We are told that the scaffold is supported at both ends, and we want to find the force on each end that is supporting the scaffold.
00:27
We'll let the brick layer have a weight of w, which is 600 newtons, and a distance d, which is 1 .5 meters from one end of the scaffold.
00:36
It has a length l of 7 meters and a weight ws, which is 800 newtons, and the pile of bricks will give the symbol wb, which is 500 newtons.
00:47
It is at a distance, capital d, 3 meters from the end of the scaffold.
00:53
Now we'll determine the net force on each end of the scaffold, which will denote by f1 and 1.
00:58
F2 and we'll choose the pivot point to be located at the end of the scaffold where the force f2 is being applied.
01:06
We'll take the counterclockwise torque as positive and clockwise torque to be negative...
