We analytically analyze finite plane strain twisting deformations of a hollow cylinder made of an isotropic and inhomogeneousMooney-Rivlinmaterial withmaterial moduli varying in the radial direction. The cylinder is deformed by applying either tangential tractions on the inner surface and tangential displacements on the outer surface or vice versa. The radial variation of the moduli is found th...

The forward scattering from an arbitrarily shaped cylinder is characterized by its induced field ratio (IFR). This paper describes how a focused beam system is used to determine the scattering characteristics of an arbitrary-shaped cylinder. The fields of the transmitting and receiving antennas, as well as the scattered field from the cylinder, are described by equivalent fundamental Gaussian b...

Abstract—Heat transfer from two cam shape cylinder in tandem arrangement had been studied numerically. The distance between the centers of cylinders (L) is allowed to vary to change the longitudinal pitch ratio (L/Deq). The equivalent diameter of the cylinder (Deq) is 27.6 mm and longitudinal pitch ratio varies in range 2<L/Deq<6. The Reynolds number based on equivalent circular cylinder are wi...

We report on the penetration of cylindrical projectiles dropped from rest into a dry, noncohesive granular medium. The cylinder length, diameter, density, and tip shape are all explicitly varied. For deep penetrations, as compared to the cylinder diameter, the data collapse onto a single scaling law that varies as the 1/3 power of the total drop distance, the 1/2 power of cylinder length, and t...

We investigate the volume preserving mean curvature flow with Neumann boundary condition for hypersurfaces that are graphs over a cylinder. Through a center manifold analysis we find that initial hypersurfaces sufficiently close to a cylinder of large enough radius, have a flow that exists for all time and converges exponentially fast to a cylinder. In particular, we show that there exist globa...

The dynamic fracture of a body is a late-stage phenomenon typically studied under simplified conditions, in which a sample is deformed under uniform stress and strain rate. This can be produced by evenly loading the inner surface of a cylinder. Due to the axial symmetry, as the cylinder expands the wall is placed into a tensile hoop stress that is uniform around the circumference. While there a...

In a paper by Stubblefield and Brinkley (I), the authors raise the question whether the observed frequencies of three categories of sections through centrioles are consistent with the assumption of random orientation of the centriole in a sectioned cell. In order to test this assumption we will compute the expected frequencies, which requires only elementary calculus, and compare them with the ...

Abstract In general two basic methods are used for controlling the velocity of a hydraulic cylinder. First by an axial variable-displacement pump for controls flow to the cylinder. This configuration is commonly known as a hydrostatic transmission. Second by proportional valve powered by a constant-pressure source, such as a pressure compensated pump, drives the hydraulic cylinder. In this stud...
