How Does Angular Motion Affect the Centrifugal Force on a Motorcar Wheel?

AI Thread Summary
The discussion centers on calculating the centrifugal force acting on a motorcar wheel with a mass of 5g attached to its 0.33m diameter rim, rotating at 521 revolutions per minute. The angular velocity is calculated as 54.6 rad/s using the formula ω = 2πN/60. The centrifugal force is expressed as F = Mω²T, but there is confusion regarding the variable T, with participants questioning if it represents torque. The conversation highlights that since the wheel is spinning at a constant speed and is balanced, the net torque is zero, indicating no additional forces are acting on it. Clarifying the role of T and the relationship between torque and the system's balance is essential for accurate calculations.

A mass of 5g is required to balance a motorcar wheel. If the mass is attached to the 0.33m diameter wheel rim, calculate the centrifugal force acting on the rim of the wheel. The speed of rotation is 521 rev/min.ω= 2∏N/60
F= M ω2 T
ω=2∏*521/60 = 54.6 rad/s
F= 5*10-3*(54.6)2*T

I am not sure how to find T and wonder if anyone can help?

What is T supposed to be?
 
torque? I am confusing myself thought I thought I would find T by using T=Ia although I would need to find I first.
So am I way out? Is it just half the diameter? 0.165
 
Which torque?
You are told that the wheel is spinning at a constant speed, and that it is balanced.
What does that tell you about the net torque?

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...
