AI Thread Summary
The discussion focuses on the mechanics of a uniform chain sliding on a fixed rough horizontal rod, specifically how friction influences the span of the chain. The key mathematical expression derived is the ratio of the extreme span to the length of the chain, given by mu log{[1+(1+mu^2)^(1/2)]/ mu}. Participants seek clarification on the system's configuration, including the positioning of the chain relative to the rod and the sliding mechanism. There is a call for visual aids or detailed explanations to better understand the problem setup. The conversation emphasizes the need for a clearer representation to facilitate solving the exercise.

The end links of a uniform chain can slide on a fixed rough horizontal rod. Show that the ratio of the extreme span to the length of the chain is

mu log{[1+(1+mu^2)^(1/2)]/ mu}





Please help me!

Either you draw a diagram, or explain in more detail how the system looks. Where is the chain wrt the rod and how it is sliding?
 
No idea, this was the text of the exercise. No picture, no explanation.
 
Does anyone know hot to solve this? Please help me!

Thread 'Variable mass system : water sprayed into a moving container'

Starting with the mass considerations #m(t)# is mass of water #M_{c}# mass of container and #M(t)# mass of total system $$M(t) = M_{C} + m(t)$$ $$\Rightarrow \frac{dM(t)}{dt} = \frac{dm(t)}{dt}$$ $$P_i = Mv + u \, dm$$ $$P_f = (M + dm)(v + dv)$$ $$\Delta P = M \, dv + (v - u) \, dm$$ $$F = \frac{dP}{dt} = M \frac{dv}{dt} + (v - u) \frac{dm}{dt}$$ $$F = u \frac{dm}{dt} = \rho A u^2$$ from conservation of momentum , the cannon recoils with the same force which it applies. $$\quad \frac{dm}{dt}...

Thread 'Struggle to understand the concept of the question (ice cube in water optics question)'

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...
