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 'Collision of a bullet on a rod-string system: query'

In this question, I have a question. I am NOT trying to solve it, but it is just a conceptual question. Consider the point on the rod, which connects the string and the rod. My question: just before and after the collision, is ANGULAR momentum CONSERVED about this point? Lets call the point which connects the string and rod as P. Why am I asking this? : it is clear from the scenario that the point of concern, which connects the string and the rod, moves in a circular path due to the string...

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:
