Two-Dimensional Force System

Two-Dimensional Force System

A two-dimensional system in mechanical engineering involves the analysis of motion and forces in a plane. A two-dimensional force vector can be resolved into its components as:

Three-Dimensional Force System

Three-Dimensional Force System

In mechanical engineering, a three-dimensional force system is a system of forces acting in three dimensions, with forces applied along the x, y, and z coordinate axes. The three-dimensional force system is an important concept in mechanical engineering, as it allows engineers to understand and analyze the behavior of objects and structures in three dimensions. By understanding the forces acting on a system, engineers can design more efficient and effective mechanical systems that can withstand...

Measurements of Strain

Measurements of Strain

Strain quantifies the deformation of a material under force, typically measured as normal strain, which represents the change in length when compared with the original length. Electrical strain gauges are used for enhanced accuracy. These devices consist of a conductive wire mounted on a paper backing that adheres to the material's surface. These gauges operate on the piezoresistive effect, where the wire's electrical resistance changes in response to mechanical deformation. The strain gauge...

Design Example: Strain Gauge Bridge or Wheatstone Bridge

The utilization of strain gauges as transducers for converting mechanical strain into electrical signals is a common practice in various engineering applications. These strain gauges are frequently integrated into Wheatstone bridge circuits to accurately measure parameters such as force or pressure. Within this context, each element within the circuit exhibits a resistance that undergoes subtle variations when subjected to mechanical strain. The primary objective is to convert minuscule...

True Stress and True Strain

True Stress and True Strain

Engineering stress is calculated as the load divided by the original, undeformed cross-sectional area. It approximates a material under load. This approximation is especially relevant post-yield in ductile materials. Though engineering stress-strain diagrams are often used for their convenience and accessibility, they can sometimes fall short in accuracy, particularly when dealing with large strain values.
In contrast, true stress offers a more precise portrayal. It is computed by dividing the...

Static and Kinetic Frictional Force

Static and Kinetic Frictional Force

One of the simpler characteristics of sliding friction is that it is parallel to the contact surfaces between systems, and is always in a direction that opposes the motion or attempted motion of the systems relative to each other. If two systems are in contact and moving relative to one another, then the friction between them is called kinetic friction. For example, kinetic friction slows a hockey puck sliding on ice.
However, if two systems are in contact and are stationary relative to one...

Area of Science:

Biomechanics
Sports Science
Neuromuscular Function Assessment

Background:

Commercial force plates are expensive and lack bilateral measurement capabilities.
Accurate assessment of lower limb neuromuscular function is crucial for sports performance.
Existing systems often use closed algorithms, limiting research flexibility.

Purpose of the Study:

To develop and validate a cost-effective, dual-channel strain gauge force plate system.
To enable synchronized bilateral countermovement jump (CMJ) kinetic assessment.
To provide an open-architecture solution for biomechanical research and sports monitoring.

Main Methods:

Developed a dual-plate system with strain gauges and hardware-triggered video synchronization.
Implemented custom software for jump phase recognition and kinetic variable calculation.
Validated the system through static mass measurements, dynamic impulse tests, video cross-validation, and test-retest reliability assessments.

Main Results:

The system demonstrated high accuracy in static and dynamic calibrations (R² > 0.99).
Test-retest reliability was excellent for key metrics like concentric impulse (ICC=0.997) and jump height (ICC=0.987).
Bilateral force differences were captured, with moderate reliability for asymmetry index (ICC=0.748).

Conclusions:

The proposed dual-channel force plate system is a valid, reliable, and affordable solution for CMJ analysis.
The open-source architecture enhances accessibility for sports performance monitoring and biomechanical research.
This system effectively synchronizes bilateral kinetic data, addressing limitations of commercial alternatives.
