On extracting momentum from supports: the bullet in the beam problem
Xiaoyu Zheng, Tianyi Guo, Peter Palffy-Muhoray
To gain insights into momentum transfer from the supporting environment, we consider the simple problem of a bullet, fired from below, into a wooden beam resting on two supports. T…
Whip dynamics in a freely falling chain
Tianyi Guo, Xiaoyu Zheng, Peter Palffy-Muhoray
In this work, we examine the whip dynamics in a freely falling chain. We consider an inextensible chain with free ends in the presence of gravity hanging from a fixed pulley. If th…
On a paradox in the impact dynamics of smooth rigid bodies
Peter Palffy-Muhoray, Epifanio G. Virga, Mark Wilkinson +1
Paradoxes in the impact dynamics of rigid bodies are known to arise in the presence of friction. We show here that, on specificc occasions, in the absence of friction, the conserva…
