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 'Rolling without slipping on a curved surface'

Kindly see the attached pdf. My attempt to solve it, is in it. I'm wondering if my solution is right. My idea is this: At any point of time, the ball may be assumed to be at an incline which is at an angle of θ(kindly see both the pics in the pdf file). The value of θ will continuously change and so will the value of friction. I'm not able to figure out, why my solution is wrong, if it is wrong .

Thread 'Voltmeter readings for this circuit with switches'

TL;DR Summary: I would like to know the voltmeter readings on the two resistors separately in the picture in the following cases , When one of the keys is closed When both of them are opened (Knowing that the battery has negligible internal resistance) My thoughts for the first case , one of them must be 12 volt while the other is 0 The second case we'll I think both voltmeter readings should be 12 volt since they are both parallel to the battery and they involve the key within what the...

Thread 'Power of a thin lens in a medium is 1/fₘ or μₘ/fₘ ?'

Here is what I tried This question was actually asked in one of our engineering entrances. The answer was 1D. My teachers say that we have to use μₘ/fₘ to get to this answer. I cannot understand why. I'll be really glad if you could tell me the exact definition of power (numerically) that works in all scenarios.
