Equilibrium sum of forces question

AI Thread Summary
The discussion revolves around a homework question related to equilibrium, specifically involving distance and weight. The original poster seeks validation for their solution approach, expressing concerns about its simplicity. A response indicates that their method is incorrect and suggests considering the tension in the rope to sum the forces on the sliding collar. The poster acknowledges the complexity they added to the problem and mentions recalculating the angle and distance involved. The conversation highlights the challenges of starting complex physics problems and the importance of correctly applying equilibrium principles.

I am just seeing if i am on the right path. A simple yes or no would be enough.
Thank you
 
No, it's not quite right. Hint: What's the tension in the rope? Then you can sum the forces on the sliding collar.
 
Thanks Doc Al
I will look at it again when i get home from work.
 
I was going about this the wrong way, making it too complicated.
1st what I did was get the angle where the rope attached to collar A and the rod, γ = cos-1 (40/50), γ=36.87 ; the to find x I just used tan36.87= 20/x  x = 20/tan36.87 so the result is x = 26.67in.
I find that I over think a problem too much but I guess that is because I find it hard to find a starting point.

Thanks
 
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...
