1. Forward reaching movements made during body rotation generate tangential Coriolis forces that are proportional to the cross product of the angular velocity of rotation and the linear velocity of the arm. Coriolis forces are inertial forces that do not involve mechanical contact. Virtually no constant centrifugal forces will be present in the background when motion of the arm generates transi...

Flies use so-called halteres to sense body rotation based on Coriolis forces for supporting equilibrium reflexes. Inspired by these halteres, a biomimetic gimbal-suspended gyroscope has been developed using microelectromechanical systems (MEMS) technology. Design rules for this type of gyroscope are derived, in which the haltere-inspired MEMS gyroscope is geared towards a large measurement band...

Nayak et al have discussed in detail the inertial forces such as Gravitational, Coriolis-Lense-Thirring and Centrifugal forces in the Kerr-Newman Space-time in the Kerr-Newman Space-time. The main theme of this paper is to study the Gravitational and Centrifugal forces in the NUT-Kerr-Newman Space-time. Keywords—Gravitational Forces, Centrifugal Forces, Nut-KerrNewman, Space time.

Subjects who are in an enclosed chamber rotating at constant velocity feel physically stationary but make errors when pointing to targets. Reaching paths and endpoints are deviated in the direction of the transient inertial Coriolis forces generated by their arm movements. By contrast, reaching movements made during natural, voluntary torso rotation seem to be accurate, and subjects are unaware...

We evaluated the combined effects on reaching movements of the transient, movement-dependent Coriolis forces and the static centrifugal forces generated in a rotating environment. Specifically, we assessed the effects of comparable Coriolis force perturbations in different static force backgrounds. Two groups of subjects made reaching movements toward a just-extinguished visual target before ro...

This application note gives an overview of different control mechanisms for MEMS Coriolis Vibratory Gyroscopes (CVG) and how they are implemented using the commercial off-the-shelf HF2LI Lock-in Amplifier. A MEMS gyroscope is a micro-machined inertial device that can measure the angle of orientation or the angular rate of rotation. The principle relies on a vibrating structure that is suspended...

Flying insects have evolved sophisticated sensory capabilities to achieve rapid course control during aerial maneuvers. Among two-winged insects such as houseflies and their relatives, the hind wings are modified into club-shaped, mechanosensory halteres, which detect Coriolis forces and thereby mediate flight stability during maneuvers. Here, we show that mechanosensory input from the antennae...

Abstract Massive stars exhibit a variety of instabilities, many which are poorly understood. We explore instabilities induced by centrifugal forces and angular momentum transport in massive rotating stars. First, we derive numerically solve linearized oscillation equations for adiabatic radial modes polytropic stellar models. In the presence differential rotation, show that Coriolis combined wi...

This work summarises the impact of Coriolis forces on the formation of a vortex ring. The initial formation of the ring and subsequent transient migration to a steady structure is described, focussing on the processes by which the transition occurs. A side-by-side comparison of vortices generated with and without the impact of Coriolis forces is made using 3 component planar velocity field data...
