Steady performance prediction of a heeled planing boat in calm water using asymmetric 2D+T model

Proceedings of the Institution of Mechanical Engineers Part M: Journal of Engineering for the Maritime Environment, 2017
This article presents a simple mathematical model for predicting the running attitude of warped planing boats fixed in a heel angle and free to trim and sinkage. The proposed model is based on asymmetric 2D+T theory utilizing a pressure equation which is

Numerical Study on Aerodynamic Characteristics of High-Speed Planing Trimaran

Applied Sciences (Switzerland), 2023
When the planing hull is sailing at high speed, the proportion of air resistance to the total resistance increases significantly. Therefore, by studying the aerodynamic characteristics of the planing hull shape, we can analyze the influence of the hull ...

Force/torque closure grasp in the plane

Proceedings IROS '91:IEEE/RSJ International Workshop on Intelligent Robots and Systems '91, 2002
For frictionless point fingers it is shown that four fingers are sufficient to constitute a force/torque closure grasp for an arbitrarily polygonal object in the plane, thus improving the best previous bound of six fingers. Since four fingers are also necessary to have force/torque closure grasp for an object with arbitrary polygon shape on the plane ...

A Concentrated Force Problem of Plane Strain or Plane Stress

Journal of Applied Mechanics, 1947
Abstract The problem in plane strain or plane stress of a large plate containing an elliptical hole, which is loaded by line forces at the ends of the minor axis of the ellipse, is solved in closed form by using complex variable analysis.

On forced vibrations of a particle in the plane

International Journal of Non-Linear Mechanics, 1968
Abstract The equations of large planar motion of a particle, restrained by two springs (identical or not) are always non-linear because of the kinematic terms, even when the springs are linear. For such a system two and only two modes of “similar” normal mode vibrations are known to exist [1].

Maximum isometric arm forces in the horizontal plane

Journal of Biomechanics, 2006
In this paper, we measured the maximum isometric force at the hand in eight directions in the horizontal plane and at five positions in the workplace. These endpoint forces were the result of shoulder horizontal adduction/abduction and elbow flexion/extension torques.

Isometric pull forces in the sagittal plane

Applied Ergonomics, 1998
This paper investigates the differences in maximal isometric horizontal pull forces in the sagittal plane about a frontal plane work envelope. Eight subjects produced maximal isometric horizontal pulls about 32 positions in the frontal for each of three different postural conditions: free standing, fixed standing and seated.
