What is the tension in the bottom hook attached? okay, so to find our tension in our bottom hook, we could draw a free body diagram for our bottom hook.
00:11
We have our tension 1, and we have our weight force, which is our 600 newtons.
00:17
In our y direction, we have tension 1 minus weight is equal to 0.
00:21
So our tension 1 is just 600 newtons in our bottom hook.
00:29
For b, we like to find how many lengths of rope support the movable pulley.
00:33
To find the amount of movable ropes, we want to look at our diagram.
00:43
We only have three ropes that support our movable pulley.
00:47
So the lengths of rope is just going to be three lengths of rope.
00:54
Now for c, what's the tension of the long rope? now we'd like to find the tension of our long rope.
01:01
To find the tension of our long rope, we have the three tensions...
