Smithd-ch11.PDF Angular Momentum

This unit discusses torque and its relationship to angular momentum, as well as the principle of the conservation of angular momentum. Torque plays the same role in rotational motion that force plays in translational motion. The right-hand rule helps determine the direction of a cross product vector. In angular momentum problems, the system will either be isolated or nonisolated. However, in a nonisolated system, net torque must be taken into consideration. Torque is measured in Newtonsmeter.

Volume 7A: Dynamics, Vibration, and Control. Virtual, Online. November 16—19, This paper proposes a new approach to stabilize the spin of a suspended litter during air ambulance rescue hoist operations. In severe cases, the spin destabilizes the suspended load, risks injury to the patient, and jeopardizes the safety of the aircrew. The presented design employs an anti-torque device to arrest the spin that is safer and faster than a tagline and is without the tactical constraints of the tagline. The device follows tailored control laws to accelerate a flywheel attached to the litter, thereby generating sufficient angular momentum to counteract the spin and stabilize the suspended litter.

Angular momentum is a fundamental conserved quantity in fluid flows, and it is neither created or destroyed inside the fluid. It can only be added or removed from the flow by torques applied at the boundaries, so accurate measurements of boundary torques provide a lot of insight into the global flow state. To understand angular momentum transport in the UMD Three Meter Geodynamo , I designed and built a wireless sensor for high-resolution measurements of the torque on the inner sphere. Most of the instrumentation on the three meter experiment is mounted on the rotating outer sphere and communicates to the stationary laboratory frame using Wi-Fi. However, the most sensitive method of measuring the inner sphere torque was to use a strain-gauge torque sensor between the inner sphere drive motor and the shaft that drives the inner sphere. The circuit here measures the torque sensor's output and transmits it to the laboratory frame. The millivolt-level output of a Futek reaction torque sensor is amplified with an LT instrumentation amplifier and digitized with a MCP bit analog-to-digital converter.

Highly efficient current-induced motion of chiral domain walls was recently demonstrated in synthetic antiferromagnetic SAF structures due to an exchange coupling torque ECT. The ECT derives from the antiferromagnetic exchange coupling through a ruthenium spacer layer between the two perpendicularly magnetized layers that comprise the SAF. Here we report that the same ECT mechanism applies to ferrimagnetic bi-layers formed from adjacent Co and Gd layers.

Prediction of the Torque Converter Characteristics by Fluid Flow Simulation

In physics and mechanics , torque is the rotational equivalent of linear force. The concept originated with the studies by Archimedes of the usage of levers. Just as a linear force is a push or a pull, a torque can be thought of as a twist to an object around a specific axis. Another definition of torque is the product of the magnitude of the force and the perpendicular distance of the line of action of a force from the axis of rotation. When being referred to as moment of force, it is commonly denoted by M. In three dimensions, the torque is a pseudovector ; for point particles , it is given by the cross product of the position vector distance vector and the force vector.

The rotation control of particles in optical tweezers is often subject to the spin or orbit angular momentum induced optical torque, which is susceptible to the mechanical and morphological properties of individual particle. Here we report on a robust and high-speed rotation control in optical tweezers by using a novel linear polarization synthesis based on optical heterodyne interference between two circularly polarized lights with opposite handedness. The synthesized linear polarization can be rotated in a hopping-free scheme at arbitrary speed determined electronically by the heterodyne frequency between two laser fields. The experimental demonstration of a trapped vaterite particle in water shows that the precisely controlled rotation frequency of Hz can be achieved. The proposed method will find promising applications in optically driven micro-gears, fluidic pumps and rotational micro-rheology. Home Journals News Conferences Jobs. Opto-Electronic Advances.
