Simple pendulum revisited [PDF]
European Journal of Physics, 2005 We describe a 8085 microprocessor interface developed to make reliable time period measurements. The time period of each oscillation of a simple pendulum was measured using this interface. The variation of the time period with increasing oscillation was studied for the simple harmonic motion (SHM) and for large angle initial displacements (non-SHM ...

A computer controlled pendulum with position readout
, 2009 We have designed, built and operated a physical pendulum which allows one to demonstrate experimentally the behaviour of the pendulum under any equation of motion for such a device for any initial conditions.

Heteroclinic Orbits for a Discrete Pendulum Equation [PDF]
, 2010 About twenty years ago, Rabinowitz showed firstly that there exist heteroclinic orbits of autonomous Hamiltonian system joining two equilibria. A special case of autonomous Hamiltonian system is the classical pendulum equation.

Anti‐Slip Material‐Based Strategies and Approaches
Advanced Materials Technologies, EarlyView.This review highlights the principle mechanisms of slipping at the microscale, linking contact mechanics with a friction behavior model for surface interfaces. Main strategies to develop anti‐slip properties to the surfaces are discussed alongside standardized testing approaches.

Nihon Kikai Gakkai ronbunshu, 2019 Recently, wave-powered electrical generators, using double-cones moving on circular rails, have been proposed. Rotational motion of the generator’s hull, induced by waves, is changed into the rotational and translational movement of either a rigid ...

Energy-Based Approach for Studying Fibre-Reinforced Concrete Subjected to Impact Loading
International Journal of Concrete Structures and Materials, 2022 In general, concrete behaves differently when the load is applied at a different speed, i.e. concrete’s mechanical parameters are strain-rate sensitive.

An accurate formula for the period of a simple pendulum oscillating beyond the small-angle regime
, 2005 A simple approximation formula is derived here for the dependence of the period of a simple pendulum on amplitude that only requires a pocket calculator and furnishes an error of less than 0.25% with respect to the exact period.

Advanced Materials Technologies, EarlyView.Transducers convert physical signals into electrical and optical representations, yet each mechanism is bounded by intrinsic trade‐offs across bandwidth, sensitivity, speed, and energy. This review maps transduction mechanisms across physical scale and frequency, showing how heterogeneous integration and multiphysics co‐design transform isolated ...

Stable Imitation of Multigait and Bipedal Motions for Quadrupedal Robots Over Uneven Terrains
Advanced Robotics Research, EarlyView.How are quadrupedal robots empowered to execute complex navigation tasks, including multigait and bipedal motions? Challenges in stability and real‐world adaptation persist, especially with uneven terrains and disturbances. This article presents an imitation learning framework that enhances adaptability and robustness by incorporating long short‐term ...
