When a solid is dipped inside a liquid, the liquid surface becomes curved near the contact. For some solid–liquid interfaces, the liquid is pulled up along the solid, while for others, the liquid surface is convex or depressed near the solid surface. This phenomenon can be explained using the concept of cohesive and adhesive forces. The adhesive force is the molecular force between molecules of different materials, that is, between the molecules of the solid and the liquid. The cohesive force...

Abdullatif, Department of Mechanical Engineering, Michigan State University, East Lansing, MI Owing to the non-linear nature of its governing laws, fluid motion induces complicated flow patterns. Understanding the nature of these patterns has been the subject of intense scrutiny for centuries. Although personal computers and supercomputers are extensively used to deduce fluid flow patterns, their capabilities are still...

Source: Ketron Mitchell-Wynne, PhD, Asantha Cooray, PhD, Department of Physics & Astronomy, School of Physical Sciences, University of California, Irvine, CA Equilibrium is a special case in mechanics that is very important in everyday life. It occurs when the net force and the net torque on an object or system are both zero. This means that both the linear and angular accelerations are zero. Thus, the object is at rest, or its center of mass is moving at a constant velocity. However, this...
FAQs
Anatomical landmarks establish the points used to represent body segments or joints, while reference axes provide the basis for calculating their relationships. Together, they determine what an angle describes in a posture or movement. Consistent landmark and axis selection is especially important when comparing individuals, experimental conditions, or phases of the same movement.
Tracking angle changes over time reveals how body segments and joints are coordinated during movement. Differences between movement phases can identify shifts in posture, alignment, or mechanical performance that a single measurement would miss. This time-based view helps researchers describe locomotion and behavior as changing biological processes rather than as isolated positions.
Comparing measured angles can reveal patterns of coordination, adaptation, and mechanical performance. Researchers may examine whether individuals or conditions show different alignments or movement patterns, then relate those differences to functional anatomy or behavior. The measurements provide quantitative evidence for describing variation without relying only on visual judgments of posture or motion.
Photographs, video recordings, and motion-capture data can provide the visual or positional information needed for analysis. Researchers identify relevant anatomical landmarks, relate body segments or joints to reference axes, and calculate the resulting angles. These sources can support either measurements of a specific posture or tracking of angle changes throughout movement.
The method supports investigations of locomotion, animal behavior, biomechanics, and functional anatomy. By quantifying posture and movement, it helps researchers compare how organisms perform under different conditions or how body configuration relates to biological function. Its broader value comes from converting visible body alignment and motion into measurements suitable for systematic comparison.
Angle measurements provide a common way to examine biological variation across several fields. In ecology and animal behavior, they can characterize movement patterns; in physiology and rehabilitation, they can describe posture or alignment; in evolutionary biology, comparisons can address adaptation and functional differences. The resulting quantitative evidence helps connect body form and movement with biological performance.
