Can /sci/ help me with a problem. I understand and got correct question 2 but question 3 I would have guessed 50kg. I would have thought that due to the rope being pulled in the same direction as the load it becomes a supporting rope, therefore 300/6 rather than 300/5 to get 50kg of equivalent force to lift the weight. Can anyone help explain why the answer is 60kg?

It does, there's a mistake or at least some kind of dumb assumption in the question.
>>
>>16969264
Divide the weight by the number of ropes that are shortening (the one you are holding lengthens as you pull more out from the first pulley).

It's 50Kg

>75 kg of force
>60 kg of force

No.

>>16969644
yeah its supposed to be newtons

>>16969264
It depends on the angles of the ropes.

toss this book away because the author is stupid motherfucker

Just (((NOOOOTICE))) the patterns because you have high IQ

In 2. its 75 because you have 5 ropes. You can get 75 by doing this: 300kg / (5ropes-1)
so in 3 just do the same thing 300kg / (6ropes - 1). Don't ask about the -1.
