AI Thread Summary
The Den Hartog criteria for tuned mass dampers involve the relationship between the mass of the damper and the total mass of the system. The distinction between the total mass (M) and the damper mass (m) is clarified, indicating that M should not include m. A reference paper is suggested for further understanding, but the user expresses uncertainty about how to apply the criteria to their specific design scenario. They are working with a system mass of 55 kg and a damper mass of 5.5 kg, with specific natural and forcing frequencies. The discussion highlights the need for clarity in the application of the Den Hartog criteria in practical design.

Homework Statement


I have been searching online but I am unable to find a site that explicitly states the Den Hartog criteria for a tuned mass damper.

What is the Den Hartog criteria?

It has
$$
\mu = m/M
$$
Is ##M## total mass of the system prior to the damper or is the total mass plus the damper mass of m?
 
Look at figure 1, it shows M and m are distinct masses so M is not in fact M+m

I am not sure on how I would design a tuned mass damper from the paper though. I am trying to design one for a system with ##M = 55## kg and a tuned mass damper weighing ##5.5## kg. The natural frequency of the system is ##\omega_n = 12.061## and the forcing function has ##\omega = 183.26##.
 
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...
