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?

I multiplied the values first without the error limit. Got 19.38. rounded it off to 2 significant figures since the given data has 2 significant figures. So = 19. For error I used the above formula. It comes out about 1.48. Now my question is. Should I write the answer as 19±1.5 (rounding 1.48 to 2 significant figures) OR should I write it as 19±1. So in short, should the error have same number of significant figures as the mean value or should it have the same number of decimal places as...

Inside this opening is a sleeve-type piston with a cross-sectional area of 1 square meter. The piston is pulled to the right at a constant speed. The pulling force is(Figure 2): F = ρshg = 1000 × 1 × 5 × 10 = 50,000 N. Figure 3: Modifying the structure to incorporate a fixed internal piston When I modify the piston...
Thread 'A cylinder connected to a hanging 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...
