What is the Equilibrium Angle of an Immersed Wooden Stick?

AI Thread Summary
The discussion centers on determining the equilibrium angle θ of a uniform wooden stick immersed in water, where the stick's density (d) is less than that of water (D). Participants explore the nature of buoyant force, questioning whether it acts at the midpoint of the stick. The problem presents multiple-choice options for the tangent of the angle θ, leading to confusion about the correct approach to solve it. Understanding the principles of buoyancy is crucial for finding the solution. The conversation emphasizes the importance of applying buoyancy concepts to analyze the equilibrium state of the stick.

Homework Statement


A uniform wooden stick of density d is completely immersed in water of density D (D>d). One end of the stick is free to rotate about a hinge which is attached to the wall of the container. In equilibrium the stick the stick makes an angle θ then tanθ is-
(a)0

(b)d/D

(c)1-d/D

(d)D/d

The Attempt at a Solution


First of all i am not understanding the nature of buoyant force. In this case can we consider it to act at the middle of the rod?

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...
