autossistema
1. A specific pattern of motion or vibration in a physical system that oscillates at a characteristic frequency, determined by the system's properties and boundary conditions
The first eigenmode of the cantilever beam corresponds to its lowest natural frequency.
O primeiro autossistema da viga em balanço corresponde à sua frequência natural mais baixa.
2. In mathematics and physics, a natural mode of oscillation where all parts of a system move with the same frequency and a fixed phase relationship
The bridge's second eigenmode was excited by the wind, causing dangerous oscillations.
O segundo autossistema da ponte foi excitado pelo vento, causando oscilações perigosas.
3. A solution to the eigenvalue problem in vibration analysis and structural dynamics
Engineers computed all eigenmodes to predict the structure's response to seismic activity.
Os engenheiros calcularam todos os autossistemas para prever a resposta da estrutura à atividade sísmica.
This is a specialized technical term used primarily in engineering, physics, and mathematics fields. It is not commonly used in everyday Brazilian or American English conversation. The term is essential in structural engineering, mechanical engineering, and vibration analysis communities in both countries.
