Morphogenesis02:19

Morphogenesis

28.3K
Plant morphogenesis—the development of a plant’s form and structure—involves several overlapping developmental processes, including growth and cell differentiation. Precursor cells differentiate into specific cell types, which are organized into the tissues and organ systems that make up the functional plant.

Body Planes01:06

Body Planes

15.5K
Body planes in anatomy are imaginary flat surfaces used as reference points to divide the body into sections for anatomical study. These planes are essential for understanding the orientation, relationships, and spatial organization of anatomical structures.
The sagittal plane is the plane that divides the body or an organ vertically into right and left sides. If this vertical plane runs directly down the middle of the body resulting in equal division, it is called the midsagittal or median...

Plastic Deformations of Members with a Single Plane of Symmetry01:21

Plastic Deformations of Members with a Single Plane of Symmetry

109
When a structural member undergoes plastic deformation due to bending, it is crucial to understand the position of the neutral axis and the stress distribution. This member, characterized by a single plane of symmetry, exhibits a uniform stress distribution, with negative stress above the neutral axis and positive stress below. Notably, the neutral axis does not align with the centroid of the cross-section. This misalignment is typical in cases where the cross-section is not rectangular or...

Composite Bodies00:55

Composite Bodies

1.1K
A composite body is a body made up of multiple parts, connected to form a larger, unified object. Each part has its own weight and center of gravity, which must be considered to determine the center of gravity of the composite body. In cases where the density or specific weight is constant, the center of gravity coincides with the centroid.
Composite bodies have widespread applications in mechanical engineering, from automobiles to aircraft to rockets. For example, an automobile wheel comprises...

Neurulation01:30

Neurulation

42.1K
Neurulation is the embryological process which forms the precursors of the central nervous system and occurs after gastrulation has established the three primary cell layers of the embryo: ectoderm, mesoderm, and endoderm. In humans, the majority of this system is formed via primary neurulation, in which the central portion of the ectoderm—originally appearing as a flat sheet of cells—folds upwards and inwards, sealing off to form a hollow neural tube. As development proceeds, the...

Mesh Analysis01:20

Mesh Analysis

717
Mesh analysis is a valuable method for simplifying circuit analysis using mesh currents as key circuit variables. Unlike nodal analysis, which focuses on determining unknown voltages, mesh analysis applies Kirchhoff's voltage law (KVL) to find unknown currents within a circuit. This method is particularly convenient in reducing the number of simultaneous equations that need to be solved.
A fundamental concept in mesh analysis is the definition of meshes and mesh currents. A mesh is a closed...

Area of Science:

  • Biomechanics
  • Engineering
  • Insect Flight

Background:

  • Insect wings exhibit remarkable adaptive shape-morphing capabilities.
  • The basal complex, a 3D structure in the proximal wing region, is hypothesized to control wing deformation quality.

Purpose of the Study:

  • To validate the hypothesis that the basal complex is critical for insect wing shape changes during flight.
  • To investigate the role of the basal complex's geometry in wing deformation.
  • To develop an engineering shape-morphing mechanism inspired by insect wings.

Main Methods:

  • Numerical modeling with systematic variations of basal complex geometric parameters.
  • Analysis of wing deformation quality and quantity under simulated flight loads.

Main Results:

  • The basal complex significantly influences both the quality and quantity of insect wing deformations.
  • Numerical models indicate wing adaptations for maximum camber under loading.
  • A novel shape-morphing mechanism inspired by the basal complex was developed.

Conclusions:

  • The basal complex is essential for adaptive wing shape changes in insects.
  • Understanding insect wing biomechanics can inform the design of efficient engineering morphing systems.
  • The developed mechanism offers potential applications for morphing blades in wind turbines.
