Stress and strain during work among women performing different work tasks
1Department of Work Physiology, Nofer Institute of Occupational Medicine, Lodz, Poland.
Summary
Physical workload in female-dominated occupations impacts work reactions, with heart rate during work being a key factor. Elevated heart rate significantly worsens working ability post-task.
Area of Science:
- Occupational Health
- Physiology
- Ergonomics
Background:
- Work intensity and physiological responses are crucial in occupational health.
- Understanding the relationship between workload and worker well-being is essential.
Purpose of the Study:
- To investigate the association between work severity, workload, and post-work fatigue and working ability in female-dominated occupations.
- To determine if physical working capacity influences the physiological strain experienced during work.
Main Methods:
- Measured work severity, relative aerobic strain, and heart rate during work.
- Assessed subjective fatigue rating and working ability changes post-work.
- Analyzed data for associations between work parameters and worker reactions.
Main Results:
- Heart rate during work correlated with work severity, not physical working capacity.
- Decreased working ability was more common than increased fatigue, independent of workload parameters.
- Higher heart rates during work (over 100 bpm, 50% max HR, or 30% HRR) significantly impaired working ability.
Conclusions:
- Physical working capacity does not appear to dictate aerobic strain percentage during work.
- Heart rate during work is a critical determinant of post-work working ability decline.
- Occupational health strategies should consider heart rate thresholds to mitigate adverse effects on working ability.

01:22Problem Solving on Stress and Strain
Stress is a quantity that describes the magnitude of a force that causes deformation, generally defined as internal force per unit area. When forces pull on an object and cause its elongation, like the stretching of an elastic band, it is called tensile stress. When forces cause the compression of an object, it is known as compressive stress. When an object is being squeezed uniformly from all sides, like a submarine in the depths of the ocean, we call this kind of stress bulk stress (or volume...
01:04Applications of Stress
Consider a structure made of a boom and a rod designed to support a load. These two components are connected by a pin and stabilized by brackets and pins. The boom and the rod are detached from their supports to assess the different stresses imposed on this structure, and a free-body diagram is drawn. Then, all the forces applied, including the load acting on the structure, are identified. The reaction forces exerted on both the boom and the rod are computed using the equilibrium equations.

01:15Stress: General Loading Conditions
To grasp the intricacy of real-world conditions where multiple loads are applied simultaneously to a structure, one might visualize a section passing through a specific point within a body, aligned parallel to the xy plane. This section is subjected to various forces, including original loads, normal forces, and shearing forces.
The shearing force, possessing potential directionality within the plane of the section, is simplified into two component forces running parallel to the x and y axes.

01:10Stress-Strain Diagram
A stress-strain diagram is a crucial tool that graphically displays a material's mechanical characteristics. This diagram is derived from a tensile test performed on a carefully prepared cylindrical specimen. The specimen has two gauge marks inscribed on its central part, and the distance between these marks is known as the gauge length. The cylindrical specimen is placed in a testing machine, which applies an increasing centric load. As this load grows, so does the gauge length. This change in...
01:28True 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...

01:13Strain Energy
Strain energy is a fundamental concept in the field of materials science and structural engineering, describing the energy absorbed by a material or structure when it is deformed under load.
Consider a rod that is fixed at one end and subjected to an axial force at the free end. This axial force induces stress within the rod, leading to its elongation. As the axial force increases, so does the elongation of the rod, illustrating a direct relationship between the force applied and the resulting...
