    Forces Weight
AI Thread Summary
The discussion centers on the forces acting on a weight stack when pulled horizontally, questioning the applicability of the formula F=MG. Participants agree that the force on the horizontal rope must support the weight, confirming the initial assumption. They note that when moving the weight vertically, the pulley system's mechanics must be considered for accurate calculations of work and power. The complexity arises from the need to account for the distance the rope is pulled, which is twice the distance the weight is lifted due to the pulley configuration. Overall, understanding the dynamics of the pulley system is crucial for precise calculations in this scenario.

Forces on a weight stack with the position of the pulleys so the weight is pulled up and the puller is moving a horizontally. Is it correct to use F=MG?

Without a diagram it's hard to say for sure, but if I'm picturing it correctly, I think the answer is yes.

The force on the horizontal rope has to support the weight of the object, so your assumption is correct. However, if you start moving the weight up or down, the pulley system has to factor into any other calculations (work, etc.).

BTW, I've moved this thread to the Homework Help forums, where all schoolwork-type questions should be posted.
 
I note that there are two lines from the weight to the pulley. That means that you will have to pull the rope on the left twice the distance you lift the weight.
 
SO to calculate work = FD is it as simple as the distance the rope is pulled * mass of the wt *g. and Power would be divided by the time it takes to pull the distance or is there something specific with a pulley system that needs to be take into account?
 
Kindly see the attached pdf. My attempt to solve it, is in it. I'm wondering if my solution is right. My idea is this: At any point of time, the ball may be assumed to be at an incline which is at an angle of θ(kindly see both the pics in the pdf file). The value of θ will continuously change and so will the value of friction. I'm not able to figure out, why my solution is wrong, if it is wrong .
TL;DR Summary: I came across this question from a Sri Lankan A-level textbook. Question - An ice cube with a length of 10 cm is immersed in water at 0 °C. An observer observes the ice cube from the water, and it seems to be 7.75 cm long. If the refractive index of water is 4/3, find the height of the ice cube immersed in the water. I could not understand how the apparent height of the ice cube in the water depends on the height of the ice cube immersed in the water. Does anyone have an...
