Force Classification01:22

Force Classification

1.0K
Forces play a crucial role in the study of physics and engineering. They are essential in describing the motion, behavior, and equilibrium of objects in the physical world. Forces can be classified based on their origin, type, and direction of action.
Contact and non-contact forces are two of the most widely used categories of forces. As the name suggests, contact forces require physical contact between two objects to act upon each other. Examples of contact forces include frictional,...

Relative Motion Analysis using Rotating Axes-Problem Solving

378
Consider a crane whose telescopic boom rotates with an angular velocity of 0.04 rad/s and angular acceleration of 0.02 rad/s2. Along with the rotation, the boom also extends linearly with a uniform speed of 5 m/s. The extension of the boom is measured at point D, which is measured with respect to the fixed point C on the other end of the boom. For the given instant, the distance between points C and D is 60 meters.
Here, in order to determine the magnitude of velocity and acceleration for point...

Absolute Motion Analysis- General Plane Motion

Visualize a drone, with its propellers spinning rapidly, hovering mid-air. The fascinating movements and operations of this drone can be comprehended by applying the principle of general plane motion.
As the drone's propellers rotate, an upward force is generated that counteracts the force of gravity, enabling the drone to lift off from the ground. This initial movement of the drone is along a straight path, representing a form of translational motion. In this phase, every point on the...

Area of Science:

  • Sports Science
  • Biomechanics
  • Artificial Intelligence

Background:

  • Cheerleading has evolved into a competitive sport, necessitating objective performance evaluation.
  • Current assessment methods for cheerleading tumbling rely on subjective judgments, posing challenges for accuracy.
  • Artificial intelligence (AI) applications in acrobatic sports analytics are limited but show significant potential.

Purpose of the Study:

  • To investigate the feasibility of using AI with inertial measurement unit (IMU) data for objective cheerleading tumbling assessment.
  • To develop and evaluate machine learning (ML) models for identifying and assessing tumbling elements.

Main Methods:

  • 16 participants from a Division I collegiate cheer team wore a single IMU at the dorsal pelvis.
  • 1102 tumbling elements were recorded over a 4-week period during practice sessions.
  • Triaxial accelerations and rotational speeds were analyzed using various ML algorithms for classification and execution evaluation.

Main Results:

  • Machine learning models demonstrated high accuracy in identifying distinct cheerleading tumbling elements.
  • The AI approach proved effective despite inter-individual variability and noise in the collected data.
  • Objective metrics for tumbling execution were successfully generated.

Conclusions:

  • AI-driven assessments using IMU data are feasible for objectively evaluating cheerleading tumbling elements.
  • This technology offers a valuable complement to traditional subjective judging methods in cheerleading and similar sports.
  • The study highlights the potential of AI to enhance performance analysis and coaching in acrobatic sports.
