Gears Kinematics Motion Rotational Rotational motion

AI Thread Summary

The discussion focuses on the kinematics of rotational motion, specifically regarding the initial velocity and time for Gear A and its implications for Gear B/Drum C. It confirms that the initial velocity (Vi=0) and time (t=12s) can indeed be assumed for Gear B/Drum C, as they are part of the same system. There is a clarification needed regarding the difference between displacement and velocity in the context of the homework question. The participants agree on the application of rotational and translational kinematics. Overall, the conversation emphasizes understanding the relationships between the gears in rotational motion.

Homework Statement

Since
Gear A
--------
Vi=0
t=12s
θ=40∏

as given in the question, can I assume that Vi=0 t=12s for Gear B/Drum C as well?
If not why?

Thanks..

You can apply rotational and translational kinematic.
For question (d) the question is displacement, answer given velocity

Thanks for the clarification.

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'

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...

Thread 'Explain this asphalt sheen'

This problem is two parts. The first is to determine what effects are being provided by each of the elements - 1) the window panes; 2) the asphalt surface. My answer to that is The second part of the problem is exactly why you get this affect. And one more spoiler:
