Stability of structures

481
In mechanical engineering, the stability of systems under various forces is critical for designing durable and efficient structures. One fundamental way to explore these concepts is by analyzing systems like two rods connected at a pivot point, O, with a torsional spring of spring constant k at the pivot point. This system is similar in appearance to a scissor jack used to change tires on a car. In this case, the arms of the linkage (equivalent to the rods in this system) are entirely vertical,...

Pole and System Stability01:24

Pole and System Stability

910
The transfer function is a fundamental concept representing the ratio of two polynomials. The numerator and denominator encapsulate the system's dynamics. The zeros and poles of this transfer function are critical in determining the system's behavior and stability.
Simple poles are unique roots of the denominator polynomial. Each simple pole corresponds to a distinct solution to the system's characteristic equation, typically resulting in exponential decay terms in the system's...

Microtubule Instability

6.0K
Microtubules are hollow cylindrical filaments having a diameter of approximately 25 nm and a length that varies from 200 nm to 25 μm. GTP-bound tubulin subunits form αβ-heterodimers for microtubule assembly. These core building blocks interact longitudinally, polymerizing into protofilaments. The protofilaments then interact with one another through lateral bonding forces to form stable cylindrical microtubules. These cylindrical filaments are dynamic as they undergo repeated...

Stability

375
The time response of a linear time-invariant (LTI) system can be divided into transient and steady-state responses. The transient response represents the system's initial reaction to a change in input and diminishes to zero over time. In contrast, the steady-state response is the behavior that persists after the transient effects have faded.
The stability of an LTI system is determined by the roots of its characteristic equation, known as poles. A system is stable if it produces a bounded...

Stability of Equilibrium Configuration: Problem Solving

982
The stability of equilibrium configurations is an important concept in physics, engineering, and other related fields. In simple terms, it refers to the tendency of an object or system to return to its equilibrium position after being disturbed. The stability of an equilibrium configuration can be analyzed by considering the potential energy function of the system and examining its behavior near the equilibrium point.
Problem-solving in the context of the stability of equilibrium configuration...

Destabilization of Microtubules

3.5K
The destabilization of microtubules can occur during different stages of the microtubule lifecycle, such as nucleation or elongation. It can take place at either end of the microtubule or in the microtubule lattices as a whole. The lifespan of individual microtubules within a cell varies according to the cell type and stage of the cell cycle. During interphase, the lifespan of the microtubule is about 30 minutes, while during cell division, it is about 15 minutes. In axonal microtubules of...

Area of Science:

  • Physics
  • Materials Science
  • Complex Systems

Background:

  • Jammed packings exhibit unique vibrational properties near the jamming transition.
  • Soft modes and vibrational density of states are key characteristics of these systems.
  • Understanding the impact of particle pinning is crucial for controlling material properties.

Purpose of the Study:

  • Investigate critical behavior of low-frequency vibrations in jammed packings with pinned particles.
  • Analyze the influence of particle pinning on soft modes and vibrational scaling.
  • Comprehensively understand these behaviors through the lens of marginal stability.

Main Methods:

  • Analysis of vibrational density of states in jammed packings.
  • Examination of soft mode behavior and spatial structure.
  • Comparison with mean-field theories and investigation of quasi-localized modes.

Main Results:

  • Soft modes form a plateau in the vibrational density of states, controlled by contact number.
  • Spatial structure of soft modes remains largely unaffected by pinning.
  • Non-Debye scaling and quasi-localized modes break down below the plateau, dependent on pinning method.

Conclusions:

  • Pinning significantly impacts vibrational properties below the soft mode plateau.
  • Observed behaviors are explained by the effect of pinning on marginal stability.
  • Findings offer a unified understanding of critical phenomena in pinned jammed packings.
