How Do I Solve This Rotational Motion Problem?

AI Thread Summary
The discussion centers on solving a rotational motion problem, with the original poster seeking assistance. They provided images of the problem and their initial attempt at a solution, questioning the validity of using tan37° in their calculations. Participants suggested recalculating the moment around points A or B and emphasized the need to consider all acting forces. Ultimately, the original poster resolved the issue by recognizing their oversight in accounting for all forces involved. The problem was successfully clarified, leading to a solution.

Try to calculate moment around point A or B. I don't think your equation tan37° is valid.

Thanks dear, I got the answer. I was making the last equation in the wrong manner. I was only considering N1 ans N2 and forgot about the other forces which are acting there.
 
The problem has been cleared.
 
Thread 'Collision of a bullet on a rod-string system: query'

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'

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...
