AI Thread Summary

To determine the maximum velocity an insect can travel on a compact disc without slipping off, the discussion focuses on the principles of circular motion and static friction. The insect, weighing 0.5g and positioned 4cm from the center, experiences centripetal force that must be balanced by the static friction force. The coefficient of static friction is given as 0.51, which is crucial for calculating the maximum velocity. Participants in the discussion emphasize the need for a free-body diagram to visualize the forces acting on the insect. Ultimately, the conversation revolves around applying the relevant equations of motion to find the insect's maximum safe speed.

A .5g insect rests on a compact disc at a distance of 4cm from the centre. If the coeffiecient of static friction is .51 what is the maximum velocity the insect can experience without slipping off?

I am lost, can someone help ?

Draw a free-body diagram for the bug.
This is circular motion at constant speed... what is the condition for that?
What are the equations?

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:
