An integrable family of torqued, damped, rigid rotors
J. A. Hanna
Expositions of the Euler equations for the rotation of a rigid body often invoke the idea of a specially damped system whose energy dissipates while its angular momentum magnitude…
Impact-induced acceleration by obstacles
N. A. Corbin, J. A. Hanna, W. R. Royston +2
We explore a surprising phenomenon in which an obstruction accelerates, rather than decelerates, a moving flexible object. It has been claimed that the right kind of discrete chain…
On the planar elastica, stress, and material stress
H. Singh, J. A. Hanna
We revisit the classical problem of the planar Euler \emph{elastica} with applied forces and moments, and present a classification of the shapes in terms of tangentially conserved…
Whirling skirts and rotating cones
Jemal Guven, J A Hanna, Martin Michael Müller
Steady, dihedrally symmetric patterns with sharp peaks may be observed on a spinning skirt, lagging behind the material flow of the fabric. These qualitative features are captured…
