    Centripetal Motion
AI Thread Summary
The discussion clarifies a common mistake in centripetal motion calculations, where the diameter was incorrectly used as the radius. The correct relationship is established as radius equals diameter divided by two. The period of motion is calculated to be 4.4 seconds, with frequency linked to angular velocity. Additionally, it emphasizes the importance of considering gravitational force acting on the rider. Accurate references on circular motion are provided for further understanding.

resolved thanks to astronuc... radius = d/2

i accidentally used the diameter as my radius

Well, let the period T = 1/f = 4.4 s.

and f = \omega /2\pi

and the centripetal force = Fc = m\omega^2r = mv2/r, where r is the radius of the circular trajectory.

Also don't forget the rider is still in a gravitational field, so don't forget the rider's weight due to gravity, mg, which is always down.

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...
