Solving Angular Acceleration: Tips and Help for Inclined Planes and Formulas

AI Thread Summary
The discussion revolves around solving problems related to angular acceleration on inclined planes, particularly focusing on a cylinder's motion. Participants emphasize the importance of creating a free body diagram (FBD) to analyze linear motion using the formula F=ma. There is confusion regarding the angular acceleration of the center of the circle, as it is suggested that with a radius of zero, angular acceleration cannot be defined. The conversation highlights the need to differentiate between linear and angular motion in such scenarios. Clarification on these concepts is essential for effectively solving the problem presented.

Tangent Acceleration, Linear Acceleration

The Attempt at a Solution



I tried to made a free body diagram but i got confused with the inclined plane I am stuck there. Also with the Formulas for the accelerations...

PLEASE SOMEONE HELP ME!

ok I've been thinking about this and i think it might be two questions in one.

first, to analyze the linear motion of the center of the circle G. i would just treat the center as a particle, and use F=ma. draw out your FBD, use that 5-12-13 triangle instead of trig functions but in the same manner, that should get you the linear acceleration.

the second part is where i am getting confused. does the center of a circle have a angular acceleration? because the first derivation of angular acceleration would be displacement, S=(theta)(radius), but here radius is equal to zero, and therefore we have no S and therefore, no angular acceleration...


just an idea...
 

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...
