Mass Spring Spring mass system System

AI Thread Summary

In a spring mass system, the angular frequency (w) is determined by the formula w = sqrt(k/m). Increasing the mass (m) reduces w, while increasing the spring stiffness (k) increases w. The amplitude of vibration does not affect w, resulting in no change. Additionally, increasing phase lag also does not impact the value of w. Overall, changes in mass and spring stiffness directly influence the angular frequency, while amplitude and phase lag do not.

1. For a given spring mass system, what would be effect on w if: a) incease size of mss, B) inceasing amplitude of vibration, C) increasing spring stiffness, D) increase phase lag

2. w= sqrt (k/m)

3. Therefore using above w = sqrt (k/m)
a. Reduces
b. no change
c. Increases
d. No change

Any coments please

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:
