Understanding and Solving Vertical Structure Stress Equations

AI Thread Summary
The discussion focuses on solving vertical structure stress equations, specifically addressing a homework problem related to stress being constant. A participant expresses confusion about the question, suggesting that the wording may need clarification to better understand the task. They propose that changing the request from determining stress to finding the radius at the top of a structure could simplify the problem. Additionally, they note the importance of having actual values for compressive strength and density of concrete to proceed effectively. Overall, the conversation highlights the need for clearer problem statements and relevant data in structural analysis.

I've been puzzling over this since you first posted the question . Part 2 does not make much sense as written .

It might make more sense if the wording ' Determine the stress at the top of H ' was changed to ' Determine the radius r at the the top of H ' and if you had actual values for the compressive strength and density of the concrete .

Finding the radius r would not actually be too difficult but our efforts might be wasted if our understanding of the question is wrong .

Sorry I can't be more helpful .

Thread 'Struggling to understand the concept of this 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...

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}...
