Do Friction Forces Exist Between a Rod and a Shaggy Bowl?

AI Thread Summary
Friction forces can exist between a rigid rod and a shaggy bowl where they make contact, depending on the surface texture. If the bowl is smooth, no friction forces are present. However, the shaggy texture introduces potential for friction, which acts as a resistance to motion. The rod's stability relies on balanced forces in both the x and y directions, indicating that friction plays a role in dynamic scenarios. Understanding the interaction between the rod and the bowl's surface is crucial for analyzing friction in this context.

A rigid rod is put in a global bowl horizontally.The bowl is shaggy.Do friction forces exist where the rod and the bowl touch?

Homework Equations





The Attempt at a Solution


If the bowl is smooth,it's clear that friction forces don't exist.But what if the bowl is not smooth?

Friction is a resistance to force. If the rod is otherwise stabilized by balanced forces x,y , then the effect of friction is not a static consideration.

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...
