Efficient Pulley System for Fabric: Reduce Effort by 1/3 | Physics Forums"

AI Thread Summary
An efficient pulley system can significantly reduce the effort required to pull fabric wrapped around a wooden rod. To achieve a reduction of effort to one-third, it's essential to examine the entire system for friction points. Implementing ball bearings or Teflon sleeves can help minimize friction, thus lowering the force needed. While no specific pulley design is suggested, addressing friction is crucial for efficiency. Optimizing the system will enhance performance and ease of use.

I would like to design an efficient pulley system to pull a fabric which is wrapped around a wooden rod. Is there any pulley system which can reduce the effort to 1/3 rd of the actual?

I have attached some images of the setup.

vaas44, Welcome to Physics Forums!

Although I cannot suggest any different pulley system to diminish the pulling effort, I will offer this: Examine the whole system for moving parts that have friction. Then install ball bearings or teflon sleeves. Reducing friction will reduce the force necessary to pull the fabric.

Good luck and Happy New Year!
 

Thread 'Average velocity as a weighted mean'

Hello everyone, Consider the problem in which a car is told to travel at 30 km/h for L kilometers and then at 60 km/h for another L kilometers. Next, you are asked to determine the average speed. My question is: although we know that the average speed in this case is the harmonic mean of the two speeds, is it also possible to state that the average speed over this 2L-kilometer stretch can be obtained as a weighted average of the two speeds? Best regards, DaTario

Thread '1:1 versus 2:1 Mechanical Advantage debate'

The rope is tied into the person (the load of 200 pounds) and the rope goes up from the person to a fixed pulley and back down to his hands. He hauls the rope to suspend himself in the air. What is the mechanical advantage of the system? The person will indeed only have to lift half of his body weight (roughly 100 pounds) because he now lessened the load by that same amount. This APPEARS to be a 2:1 because he can hold himself with half the force, but my question is: is that mechanical...

Thread 'Newton's first law?'

Some physics textbook writer told me that Newton's first law applies only on bodies that feel no interactions at all. He said that if a body is on rest or moves in constant velocity, there is no external force acting on it. But I have heard another form of the law that says the net force acting on a body must be zero. This means there is interactions involved after all. So which one is correct?
