Normal and tangential acceleration

AI Thread Summary
Normal acceleration is essential for maintaining circular motion, calculated using the formula ω²r, where ω is the angular velocity. The discussion highlights confusion regarding the value of normal acceleration being stated as 6 rad/s², which is not explicitly mentioned in the problem. The importance of understanding both normal and tangential acceleration in rotational dynamics is emphasized. Additionally, resources like textbooks and hyperphysics are suggested for further clarification on rotational kinematics. Understanding these concepts is crucial for solving problems involving circular motion effectively.

Homework Statement


why the normal acceleration is 6 rads^-1 ? It's not stated in the question , right?
Can someone explain more about normal acceleration? i couldn't understand it . I only know that when the rod is rotated , it has tangential acceleration

It's not stated in the question. But not in the solution either! Something has to keep G in a circular trajectory and that requires an acceleration ##\ \omega^2 r.\ \ \ ## That ##\,\omega## is given in the problem statement!

For the kinematics of rotational motion: this (only the comparison), that or any textbook ! Did I forget hyperphysics?

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...
