Measuring Acceleration Due to Gravity01:12

Measuring Acceleration Due to Gravity

1.4K
Consider a coffee mug hanging on a hook in a pantry. If the mug gets knocked, it oscillates back and forth like a pendulum until the oscillations die out.
A simple pendulum can be described as a point mass and a string. Meanwhile, a physical pendulum is any object whose oscillations are similar to a simple pendulum, but cannot be modeled as a point mass on a string because its mass is distributed over a larger area. The behavior of a physical pendulum can be modeled using the principles of...

Average Acceleration01:30

Average Acceleration

15.8K
The importance of understanding acceleration spans our day-to-day experiences, as well as the vast reaches of outer space and the tiny world of subatomic physics. In everyday conversation, to accelerate means to speed up. For instance, we are familiar with the acceleration of our car; the harder we apply our foot to the gas pedal, the faster we accelerate. The greater the acceleration, the greater the change in velocity over a given time. Acceleration is widely seen in experimental physics. In...

Gyroscope01:02

Gyroscope

4.5K
A gyroscope is defined as a spinning disk in which the axis of rotation is free to assume any orientation. When spinning, the orientation of the spin axis is unaffected by the orientation of the body that encloses it. The body or vehicle enclosing the gyroscope can be moved from place to place, while the orientation of the spin axis remains the same. This makes gyroscopes very useful in navigation, especially where magnetic compasses cannot be used, such as in crewed and crewless spacecraft,...

Relative Motion Analysis - Acceleration01:10

Relative Motion Analysis - Acceleration

1.0K
A slider-crank mechanism converts rotational motion from the crank into linear motion of the slider or vice versa. This mechanism consists of three main parts: the crank, the connecting rod, and the slider. The movement of the slider-crank is an example of general plane motion as the fluctuating angle between the crank and the connecting rod. Consider a segment AB where point A is at the end of the slider and point B is on the diametrically opposite end to point A, on a crack. The variance in...

Angular Velocity and Acceleration01:11

Angular Velocity and Acceleration

12.5K
We previously discussed angular velocity for uniform circular motion, however not all motion is uniform. Envision an ice skater spinning with their arms outstretched; when they pull their arms inward, their angular velocity increases. Additionally, think about a computer's hard disk slowing to a halt as the angular velocity decreases. The faster the change in angular velocity, the greater the angular acceleration. The instantaneous angular acceleration is defined as the derivative of...

Gyroscope: Precession01:24

Gyroscope: Precession

5.9K
Precession can be demonstrated effectively through a spinning top. If a spinning top is placed on a flat surface near the surface of the Earth at a vertical angle and is not spinning, it will fall over due to the force of gravity producing a torque acting on its center of mass. However, if the top is spinning on its axis, it precesses about the vertical direction, rather than topple over due to this torque. Precessional motion is a combination of a steady circular motion of the axis and the...

Area of Science:

  • Aerospace Medicine
  • Biomedical Engineering
  • Exercise Physiology

Background:

  • Wearable accelerometers are common in exercise physiology and healthcare but lack validation in extreme operational settings.
  • Extreme environments, such as high-performance aircraft, present unique challenges for validating sensor technology.

Purpose of the Study:

  • To correlate G-force measurements from wearable accelerometers with those from high-performance aircraft.
  • To assess the feasibility and accuracy of using consumer-grade accelerometers in aviation.

Main Methods:

  • Compared two commercial wearable accelerometers against the F/A-18 Carrier Aircraft Inertial Navigation System (CAINS-2) during 20 Navy Blue Angels flights.
  • Collected 25,700 seconds of comparative data across 10 flights.
  • Administered post-flight questionnaires on perceived distractibility.

Main Results:

  • Both wearable accelerometers showed strong correlations with the F/A-18's Gz axis (r = 0.92 and r = 0.93).
  • The average vector magnitude correlation between the two accelerometers was high (r = 0.93).
  • Accelerometers were found to be minimally distracting to pilots.

Conclusions:

  • Wearable accelerometers are a valid tool for detecting G forces in high-performance aircraft.
  • This technology can provide valuable in-flight physiological data, potentially advancing aeromedical research.
