The Falling Slinky
Consider a slinky that is held at one end while the rest of it is allowed to hang freely. If the slinky is released, then as it falls due to gravity it also shrinks in extent due to the contracting force in the slinky itself. A few years ago it was discovered that the net effect of these two changes exactly counteract each other at the bottom extent of the slinky and therefore the bottom of the...
متن کاملModeling Methods for the Highly Dispersive Slinky Spring: a Novel Musical Toy
The ’Slinky’ spring is a popular and beloved toy for many children. Like its smaller relatives, used in spring reverberation units, it can produce interesting sonic behaviors. We explore the behavior of the ’Slinky’ spring via measurement, and discover that its sonic characteristics are notably different to those of smaller springs. We discuss methods of modeling the behavior of a Slinky via th...
متن کاملNumerical Modeling of Slinky-coil Horizontal Ground Heat Exchangers Considering Snow Coverage Effects
The number of Slinky-coil horizontal ground heat exchangers (HGHEs) has been increasing in geothermal heat pump (GHP) systems due to the low initial cost. The performance of the Slinky-coils, however, has not been successfully predicted with good accuracy since the complicated shape of the Slinky-coils is not easy to model either analytically or numerically. To enable this, Fujii et al. (2012) ...
متن کاملModeling the Vertical Falling Life Chute
Stretchable woven chute is a safe device for falling humans from multi-story buildings in emergencies. During the fall, the elastomeric property of the fabric, in the weft direction, causes radial forces towards the human body inside .These radial forces lead to frictional forces between the chute and the body. The falling man can reduce the falling speed by exerting outward forces via stretchi...
متن کاملNovel lincRNA SLINKY is a prognostic biomarker in kidney cancer
Clear cell renal cell carcinomas (ccRCC) show a broad range of clinical behavior, and prognostic biomarkers are needed to stratify patients for appropriate management. We sought to determine whether long intergenic non-coding RNAs (lincRNAs) might predict patient survival. Candidate prognostic lincRNAs were identified by mining The Cancer Genome Atlas (TCGA) transcriptome (RNA-seq) data on 466 ...
