Water Pressure in tank filled with water

AI Thread Summary
The discussion focuses on ranking the force exerted on five horizontal floors in a water-filled tank based on their depths. The force is determined by the height of the water column above each floor, with deeper floors experiencing greater pressure. The correct ranking from greatest to least force is e, b, d, a, c, as they are positioned at distances L, 2L, and 3L below the tank's top. The relevant equations for calculating pressure and force are p = hρg and F = pA. Understanding these principles is essential for accurately determining the forces acting on the floors.

Figure 14-24 shows a tank filled with water. Five horizontal floors and ceilings are indicated;
all have the same area and are located at distances L, 2L, or 3L below the top of the tank. Rank them according to the force on them due to the water, greatest first.

Are we just comparing the heights?
So e>b=d>a=c?

Thanks!

Yes, essentially, since they're all of the same area and in the same horizontal orientation. The answer is correct.

If you need to show working, the key points to include are the equations p = h{\rho}g and F = pA.
 
Thank you Curious3141! :)
 
Thread 'Collision of a bullet on a rod-string system: query'
In this question, I have a question. I am NOT trying to solve it, but it is just a conceptual question. Consider the point on the rod, which connects the string and the rod. My question: just before and after the collision, is ANGULAR momentum CONSERVED about this point? Lets call the point which connects the string and rod as P. Why am I asking this? : it is clear from the scenario that the point of concern, which connects the string and the rod, moves in a circular path due to the string...
Thread 'A cylinder connected to a hanged mass'
Let's declare that for the cylinder, mass = M = 10 kg Radius = R = 4 m For the wall and the floor, Friction coeff = ##\mu## = 0.5 For the hanging mass, mass = m = 11 kg First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on. Force on the hanging mass $$mg - T = ma$$ Force(Cylinder) on y $$N_f + f_w - Mg = 0$$ Force(Cylinder) on x $$T + f_f - N_w = Ma$$ There's also...
