Hi there, so for this problem, we are told that a window washer is standing on a skull fold supported by a vertical rope at each end.
00:12
Now, the skull fold weights 197 and it is 3 .60 meters long, as is shown in this figure.
00:23
Also, we need to assume that the 712 newton's worker stands at a 106 meters.
00:30
Distance that is 1 .17 meters from one end of the skullful.
00:38
So in this for this problem we are asked what is the force on the rope that is farther from the worker.
00:46
So what we need to find is the tension too.
00:53
Now first i'm going to write all of the information that we are given for this problem.
00:59
So we are given the weight of the of the man, we're gonna call this the force of the man that is equal to 712 newtons.
01:11
We're also given the weight of this skullfall that is equal to 197 newtons.
01:23
Now we're gonna call the distance, the length of the skull fold as the distance d and this is equal.
01:36
To 3 .6 meters.
01:39
Now the distance from the tension 1 to the man, that distance is the one here, 1 .17 meters.
01:53
And the other distance is the distance from that end of the skull font and the center of mass of the skull font that we know is from this figure 1 .8 meters, because it's half of the length of the scullfin.
02:15
So to find the temption 2, we're going to choose the temption 1 as a pivot, as a pivot point.
02:33
So when we do that, we obtain that a torque produced by this temption 1 is equal to 0.
02:41
So with that said, what we are going to do is to sum all of the torts in this...
