What is the definition of the D-Offset in the Parallel Axis Theorem?

AI Thread Summary
The D-offset in the Parallel Axis Theorem refers to the distance from the axis of rotation to the center of mass of the object. The equation I = Icm + Md^2 illustrates how the moment of inertia is adjusted based on this distance. The discussion emphasizes that this offset is specifically the distance of the center of mass from the chosen axis of rotation. Clarification is sought on the terminology and application of this concept in physics. Understanding the D-offset is crucial for accurately calculating moments of inertia in rotational dynamics.

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...
