How can I approach this rotational equilibrium problem?

AI Thread Summary
The discussion centers on a rotational equilibrium problem involving forces and moment arms. The participant expresses difficulty in visualizing the problem and identifying the normal forces at play. They acknowledge that normal forces act perpendicular to the moment arms extending from the pivot point. The conversation highlights the importance of understanding the relationship between forces and their moments in solving such problems. Clarity on these concepts is essential for approaching the solution effectively.

The Attempt at a Solution



I don't know where to begin. Where are the normal forces acting? I am just can't visualize this problem and it has me stumped.

A normal force acts normal (perpendicular) to the moment arm on which it acts. The moment arms extend from the pivot to the point of interaction.

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...
