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?
>>16969264It does, there's a mistake or at least some kind of dumb assumption in the question.
>>16969264Divide 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).
>>16969264It's 50Kg
>>16969264>75 kg of force>60 kg of force
>>16969641No.
>>16969644yeah its supposed to be newtons
>>16969264It depends on the angles of the ropes. toss this book away because the author is stupid motherfucker
>>16969264Just (((NOOOOTICE))) the patterns because you have high IQIn 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.
