How Is Net Torque Calculated on a Rotating Sphere?

AI Thread Summary
Net torque on a rotating sphere is calculated by applying the rotational form of Newton's second law, which relates torque to angular acceleration. The discussion emphasizes the importance of maintaining the focus on rotational dynamics rather than reverting to translational motion equations like F=ma. It highlights the need to correctly identify the relationship between torque, moment of inertia, and angular acceleration. Understanding these concepts is crucial for solving problems involving rotating objects. Accurate application of these principles leads to a correct calculation of net torque.

You started out correctly by determining the angular acceleration, but then you reverted back to translational motion using F=ma. What's the form of Newton 2 applied to rotating objects that are accelerating?
 

Thread 'Errors and significant figures'

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'

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...
