The problem of a cylinder of mass m and radius r, with its centre of mass out of the cylinder’s axis, rolling on an inclined plane that makes an angle α with respect to the horizontal, is analysed. The equation of motion is partially solved to obtain the site where the cylinder loses contact with the inclined plane (jumps). Several simplifications are made: the analysed system consists of an homogeneous disc with a one-dimensional straight line mass parallel to the disc axis at a distance y < r…

Modeling and experimentation with asymmetric rigid bodies: a variation on disks and inclines
We study the ascending motion of a disk rolling on an incline when its centre of mass lies outside the disk axis. The problem is suitable as laboratory project for a first course in mechanics at the…
Librational motion of asymmetric rolling bodies and the role of friction force
We designed a very simple asymmetric rolling spool and we studied it experimentally, in the librational regime, by using a video camera and video analysis software. Comparison of experimental results…
The surprising rolling spool: librational motion and failure of the pure rolling condition
In a previous work (Onorato P, Malgieri M, Mascheretti P and De Ambrosis A 2014 The surprising rolling spool: experiments and theory from mechanics to phase transitions Eur. J. Phys. 35 055011) an…
The surprising rolling spool: experiments and theory from mechanics to phase transitions
An asymmetric rolling spool can be investigated as a simple model for a second-order phase transition. At low energy it undergoes librational motion around the equilibrium position, whereas at high…
Ascending Disk: Theoretical and Numerical Study
TLDR
This work analyzed a classical mechanical problem: a disc with a circular hole rotating and ascending on a inclined plane to show the basic equations in both Lagrangian and Newtonian formalisms and to present numerical solutions.
The eccentric disk and its eccentric behavior
Providing example problems that stimulate curiosity and cultivate intuition among students is a prominent responsibility for physics educators. A concept that can be particularly challenging for…
Tautochrone and Brachistochrone Shape Solutions for Rocking Rigid Bodies
Rocking rigid bodies appear in several shapes in everyday life: As furniture like rocking chairs and rocking cradles or as toys like rocking horses or tilting dolls. The familiar rocking motion of…
Use of Dimensional Analysis in the X-, Y-, and Z-Axis to Predict Occurrence of Injury in Human Stampede
TLDR
Real-time video-analysis monitoring of high capacity events or those with known nozzle effects for loss of proxemics and Z-axis displacement pathology offers the opportunity to prevent mortality from human stampedes.

Rules for rolling as a rotation about the instantaneous point of contact
It is a widespread misunderstanding in introductory physics courses that the motion of rolling bodies in general can be calculated using the point of contact as a reference point when equating the…

Experiments and computer simulations show that when a rigid ball with inhomogeneous but symmetric density distribution rolls on an inclined track, it tends to adjust its orientation to rotate about…

Theoretical and experimental results are compared for the rolling motion of cylinders on a ramp. An asymmetric distribution of the mass makes the motion jerky and complex and is an interesting and…

Dynamics of Multibody Systems
TLDR
This paper presents a meta-modelling procedure that automates the very labor-intensive and therefore time-heavy and therefore expensive and expensive process of designing and implementing Rigid Body Kinematics Systems.
