Design Example: Calculating Safe Diameter for Wind-Exposed Disc01:17

Design Example: Calculating Safe Diameter for Wind-Exposed Disc

Assessing safety in wind-exposed installations is crucial to preventing potential failures. This example explores the calculation and design adjustments needed to mount a circular disc on a building facade, where wind forces are a primary concern. A 4-meter diameter disc was initially designed as an aesthetic feature facing winds at a velocity of 25 meters per second, with an air density of 1.25 kilograms per cubic meter. Given these conditions, the drag force on the disc was determined using...
Eccentric Loading01:16

Eccentric Loading

Eccentric loading is a crucial concept in the study of structural engineering and mechanics, particularly when analyzing the stability and stress distribution in columns. Unlike centric loading, where the force is applied along the centroidal axis, causing uniform compression, eccentric loading occurs when a force is applied off-center. This off-center application introduces not only direct compressive stress but also bending stress, significantly influencing the column's behavior under load.
Eccentric Axial Loading in a Plane of Symmetry01:16

Eccentric Axial Loading in a Plane of Symmetry

Eccentric axial loading occurs when an axial load is applied away from the centroidal axis of a structural member. This scenario is common in engineering, where structural elements may not be directly aligned due to various design or functional requirements.
Composite Bodies00:55

Composite Bodies

A composite body is a body made up of multiple parts, connected to form a larger, unified object. Each part has its own weight and center of gravity, which must be considered to determine the center of gravity of the composite body. In cases where the density or specific weight is constant, the center of gravity coincides with the centroid.
Composite bodies have widespread applications in mechanical engineering, from automobiles to aircraft to rockets. For example, an automobile wheel comprises...
Bearings: Problem Solving01:24

Bearings: Problem Solving

Understanding the calculations and concepts related to double-collar bearings is essential for engineers and designers to optimize the performance of these components in various applications. By analyzing the bearing under different conditions, one can ensure that it can withstand the forces and moments experienced during operation. This knowledge enables better decision-making when designing and selecting bearings for specific purposes and configurations. Consider a double-collar bearing with...
Design of Transmission Shafts - Stress Analysis01:15

Design of Transmission Shafts - Stress Analysis

Designing a transmission shaft requires a thorough understanding of the stresses induced by bending moments and torques, especially in systems where power is transferred through gears. These forces create force-couple systems at the centers of the shaft's cross-sections, leading to both transverse and torsional loading. Although shearing stresses from transverse loads are typically smaller than those from torques and are often overlooked, the significant normal stresses from these loads...

Area of Science:

  • Sports Science
  • Exercise Physiology
  • Biomechanics

Background:

  • The traditional Wingate test assesses anaerobic performance using cycle ergometers.
  • Elliptical trainers recruit larger muscle groups, potentially enhancing power output during anaerobic testing.
  • Previous research utilized electromagnetically braked elliptical trainers, necessitating a simpler mechanical modification.

Purpose of the Study:

  • To modify an elliptical trainer with a mechanical brake system for anaerobic testing.
  • To identify the optimal workload for the modified elliptical trainer Wingate test (EWT).
  • To evaluate the retest reliability and validity of the EWT using physiological markers like delta lactate.

Main Methods:

  • Thirty male university athletes performed Wingate tests on a mechanically braked elliptical trainer.
  • Workloads were tested at 12-24% body mass to determine the optimal load.
  • Peak power, average power, minimum power, power drop, fatigue index, and delta lactate were measured.

Main Results:

  • An 18% body mass workload significantly increased peak power, average power, power drop, fatigue index, and delta lactate compared to other loads (p < 0.05).
  • The EWT demonstrated high test-retest reliability for all measured anaerobic performance variables (r = 0.81–0.98).
  • The 18% body mass workload yielded optimal and reliable anaerobic power and capacity outcomes.

Conclusions:

  • A mechanically braked elliptical trainer effectively measures anaerobic power and capacity.
  • An 18% body mass workload is optimal for the EWT, providing maximal and reliable results.
  • The EWT offers a potentially more comprehensive anaerobic assessment than traditional cycle ergometers due to greater muscle engagement.
