RISPlanar Vibration of an Elastica Arch: Theory and Experiment
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This investigation examines the planar, linear vibration of a deep arch that is described by a simply supported elastica. The arch is formed from an elastic rod that buckles nonlinearly under ...
Linear Dynamics of a Translating String on an Elastic Foundation
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper examines the free and forced linear response of a string which is translating across an elastic foundation. Exact solutions are derived for the free vibration of the string which ...
Local and Global Bifurcation Analyses of a Spatial Cable Elastica
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper focuses on a boundary value problem governing the equilibrium of a slender cable subject to thrust, torsion, and gravity. In the absence of field (gravity) loading, this boundary ...
Harmonically Forced Wave Propagation in Elastic Cables With Small Curvature
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This study presents an investigation of coupled longitudinal-transverse waves that propagate along an elastic cable. The coupling considered derives from the equilibrium curvature (sag) of the ...
Effect of Loop Shape on the Drag-Induced Lift of Fly Line
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This note explains why casting a loop with a positive angle of attack is advantageous in distance fly casting. Several loop shapes, one with a positive angle of attack, one with a negative ...
Experimental Investigation of Isolated and Simultaneous Internal Resonances in Suspended Cables
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The near resonant response of suspended elastic cables driven by harmonic, planar excitation is investigated experimentally. Measurements of large amplitude cable motions confirm previous theoretical ...
Nonlinear Periodic Response of Engine Accessory Drives With Dry Friction Tensioners
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Belt drives have long been utilized in engine applications to power accessories such as alternators, pumps, compressors and fans. Drives employing a single, flat, “serpentine belt” tensioned by ...
Electrostatics and Self-Contact in an Elastic Rod Approximation for DNA
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Deoxyribonucleic acid (DNA) is an essential molecule that enables the storage and retrieval of genetic information. In its role during cellular processes, this long flexible molecule is significantly ...
Nonlinear Spatial Equilibria and Stability of Cables Under Uni-axial Torque and Thrust
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Low tension cables subject to torque may form complex three-dimensional (spatial) equilibria. The resulting nonlinear static deformations, which are dominated by cable flexure and torsion, may ...
Closed-Form Vibration Analysis of Sagged Cable/Mass Suspensions
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A theoretical model is presented which describes the three-dimensional nonlinear motion of a sagged cable that supports an array of discrete masses. An asymptotic form of this general model is ...
