How Does Adding a Weight Affect the Center of Mass of a Wheel?

AI Thread Summary
The discussion focuses on calculating the center of mass of a weighted wheel, specifically a 6.0 kg wheel with a 2.0 kg weight placed 24 cm from its center. The calculation shows that the center of mass is located 0.06 m away from the center, towards the side with the weight. This indicates that the added weight shifts the center of mass off-center, impacting the wheel's rotational inertia. The shift will influence the wheel's response to external forces. Overall, the calculation and its implications for the wheel's dynamics are confirmed as accurate.

A thin 6.0 kg wheel of radius 30 cm is weighted to one side by a 2.0 kg weight, small in size, placed 24 cm from the center of the wheel.
Calculate the position of the center of mass of the weighted wheel.

Here's what I have so far.
I set the origin as the center of the wheel.

Center of Mass = (6kg*0m)+(2kg*.24m)/8kg = 0.06m away from the center.

Is that correct?

Looks good to me.
 


Yes, your calculation for the position of the center of mass is correct. The center of mass of the weighted wheel is located 0.06m away from the center of the wheel, towards the side where the weight is placed. This means that the center of mass is not located at the exact center of the wheel, but slightly off to one side due to the added weight. This shift in the center of mass will affect the rotational inertia of the wheel and how it responds to external forces.
 
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...
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...
