Vibrating Concrete01:19

Vibrating Concrete

1.4K
Mechanical vibrators are instrumental in compacting newly poured concrete within formwork and around reinforcements. This process is essential to eliminate trapped air pockets and establish a dense concrete mass. One widely used method is vibrating by internal vibrators, often referred to as a poker vibrator or immersion vibrator. It is rapidly inserted through the full depth of the freshly laid concrete and slightly extends into the layer below it (which remains in a plastic state). Consistent...

Stress Concentrations in Circular Shafts

700
Consider the elastic torsion formula, which applies to a circular shaft with a consistent cross-section. This formula assumes that the shaft's ends are loaded with rigid plates firmly attached. However, in many cases, torques are applied to the shaft through mechanisms like flange couplings or gears, which are connected by keys inserted into keyways. This application method modifies the stress distribution near the point of torque application, causing it to deviate from the distributions...

Virtual Work for a System of Connected Rigid Bodies01:06

Virtual Work for a System of Connected Rigid Bodies

859
Virtual work is a powerful method used to solve problems involving several connected rigid bodies. When the system is in equilibrium, virtual work is zero. This allows the calculation of the resulting forces when a system undergoes a virtual displacement. When attempting to analyze such a system, first, use a free-body diagram, where an independent coordinate represents the configuration of the links, and mark its deflected position resulting from the positive virtual displacement.
Next,...

Area of Science:

  • Occupational Health and Safety
  • Biomedical Engineering
  • Human Factors Engineering

Background:

  • Effective workplace management of whole-body vibration (WBV) exposure necessitates systematic data collection.
  • High cost and complexity of commercial measurement devices hinder routine data acquisition in workplaces.

Purpose of the Study:

  • To develop and validate a cost-effective iOS application for measuring WBV exposure.
  • To assess the utility of an iPod Touch-based application as a screening tool for WBV risks.

Main Methods:

  • An iOS application (WBV) was developed for an iPod Touch to measure WBV.
  • Simultaneous WBV measurements were taken using the iOS app and a commercial device across various vehicles and mobile plant.
  • 98 paired measurements were collected at a surface coal mine.

Main Results:

  • The iOS application demonstrated a 95% confidence interval of +/- 0.077 m/s(2) r.m.s. constant error for vertical direction.
  • The application accurately identified situations within the ISO2631.1 health guidance caution zone.
  • Qualitative features of frequency spectra were successfully reproduced.

Conclusions:

  • The low-cost, simple iOS application can serve as a valuable screening tool for WBV exposure.
  • Facilitates identification of workplace scenarios potentially leading to musculoskeletal disorders.
  • Enhances accessibility of WBV data collection for improved occupational health management.
