Shear on the Horizontal Face of a Beam Element01:16

Shear on the Horizontal Face of a Beam Element

133
To understand shear on the flat side of a prismatic beam element, consider the vertical and horizontal shearing forces, and the normal forces, acting on the element. The element's upper (U) and lower (L) sections, which are divided by the beam's neutral axis, are examined. The equilibrium of these forces is determined by applying the equilibrium equation, which helps identify the horizontal shearing force. This force is directly related to the bending moments and the cross-section's...

Deformations in a Transverse Cross Section01:21

Deformations in a Transverse Cross Section

162
When a material is subjected to uniaxial stress, it elongates or contracts in the direction of the applied force, and also undergoes changes in the perpendicular directions. This behavior is crucial for understanding how materials behave under stress and is governed by mechanical properties such as Poisson's ratio v, which measures the ratio of transverse strain to axial strain.
As the material stretches, it expands or contracts in orthogonal directions to the load. This phenomenon varies...

Composite Masonry Walls01:18

Composite Masonry Walls

509
Composite masonry walls combine multiple wythes of the same or different masonry materials to create a unified structure. These walls feature wythes that are bonded together either through mortar-filled collar joints, grouted spaces, or more commonly, with rigid metal ties and reinforcements, with the use of masonry header units being rare. Metal ties are preferred because they effectively minimize water penetration, as these walls primarily absorb moisture and then release it into the...

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

Plastic Deformations of Members with a Single Plane of Symmetry

85
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...

Vertical Curve: Problem Solving

19
Vertical curves provide the transition between two roadway grades, ensuring safety, comfort, and functionality. Calculating elevations at specific stations along the curve involves several systematic steps based on the curve's geometry and provided design parameters.The vertical curve is defined by its length, grades, Point of Vertical Intersection (P.V.I.) location, and P.V.I. elevation. The stations of the Point of Vertical Curvature (P.V.C.), where the curve begins, and the Point of Vertical...

Introduction to Vertical Curves01:24

Introduction to Vertical Curves

16
Vertical curves are parabolic transitions that connect different grades on highways and railroads, ensuring a smooth alignment between back and forward tangents. The back tangent represents the initial grade, while the forward tangent defines the subsequent grade. These curves can be symmetrical, with equal tangent lengths, or nonsymmetrical, with varying lengths. The key points defining a vertical curve include the Point of Vertical Intersection (P.V.I.), where the tangents meet; the Point of...

Area of Science:

  • Cognitive Psychology
  • Neuroscience
  • Visual Perception

Background:

  • The composite face effect (CFE) provides evidence for holistic face processing.
  • Holistic processing integrates facial features into a unified whole.
  • The horizontal CFE is well-studied, but the vertical CFE is less understood.

Purpose of the Study:

  • To investigate the existence and characteristics of the vertical composite face effect (CFE).
  • To compare the vertical CFE with the established horizontal CFE.
  • To explore the influence of attention on the CFE.

Main Methods:

  • Created composite stimuli using aligned and misaligned halves of familiar and unfamiliar faces.
  • Participants made familiarity judgments on vertical and horizontal composites.
  • Manipulated attention to specific face halves.

Main Results:

  • Misaligned composites led to more accurate and faster familiarity judgments than aligned composites.
  • The vertical CFE magnitude was comparable to the horizontal CFE.
  • CFE size decreased when attention was not focused on a specific face half.

Conclusions:

  • Both vertical and horizontal CFEs exist, supporting holistic face processing.
  • A common mechanism integrates facial information across the visual field.
  • Holistic processing is fundamental to face recognition.
