AI Thread Summary
Calculating the impact force of a pendulum in g's is complex due to the variable deformation of the material during collision. The impact force is influenced by the energy absorbed by the sample, which is typically measured in terms of fracture energy. Standard methods like the Charpy impact test can provide insights into these measurements. There is no straightforward formula for calculating g forces in this context. Understanding the material's response to impact is crucial for accurate assessments.

I need to run an experiment using a swinging steel ball pendulum to impact diffrent materials to determine impact integrity in g's.
What is the formula for this? In g (x times gravity)

Thread 'Is calling fictitious forces "not real" just about terminology?'

Hi there, im studying nanoscience at the university in Basel. Today I looked at the topic of intertial and non-inertial reference frames and the existence of fictitious forces. I understand that you call forces real in physics if they appear in interplay. Meaning that a force is real when there is the "actio" partner to the "reactio" partner. If this condition is not satisfied the force is not real. I also understand that if you specifically look at non-inertial reference frames you can...

Thread 'Derivation of Hamilton's Principle: Questions'

I have recently been really interested in the derivation of Hamiltons Principle. On my research I found that with the term ##m \cdot \frac{d}{dt} (\frac{dr}{dt} \cdot \delta r) = 0## (1) one may derivate ##\delta \int (T - V) dt = 0## (2). The derivation itself I understood quiet good, but what I don't understand is where the equation (1) came from, because in my research it was just given and not derived from anywhere. Does anybody know where (1) comes from or why from it the...
