Working Stress Design (WSD) is a design methodology that is commonly used in civil engineering and structural design. It involves the use of stress analysis techniques to determine the maximum stress that a material can withstand under a given load, and then designing the structure to ensure that the actual stress is less than this maximum value. WSD is based on the assumption that materials have a linear elastic behavior, which means that the stress and strain are proportional to each other within the elastic limit of the material. The WSD approach involves selecting a factor of safety that is applied to the maximum stress value to ensure that the structure can withstand the loads it will be subjected to during its lifetime. This factor of safety is typically based on the level of uncertainty in the design process, the consequences of failure, and the level of risk that is acceptable to the designer and the client. One of the key advantages of WSD is that it allows designers to use simple and well-established analytical methods to calculate the stresses and deflections in a structure. This can lead to more efficient designs that are easier to construct and maintain. However, WSD has some limitations, including the fact that it does not account for the non-linear behavior of materials beyond their elastic limit, and it does not take into account the effects of fatigue or long-term creep. In summary, Working Stress Design is a widely used design methodology in civil engineering and structural design that involves the use of stress analysis techniques to ensure that a structure can withstand the loads it will be subjected to during its lifetime. It is based on the assumption of linear elastic behavior of materials and involves selecting a factor of safety to ensure that the structure is safe and reliable. While it has some limitations, WSD remains an important tool for structural designers and engineers.

Working Stress Design (WSD) is a design methodology that draws on a combination of theoretical and practical approaches to product design. WSD places an emphasis on the use of ergonomics and scientific principles to create products that are both aesthetically pleasing and efficient. The goal of WSD is to create a product that will be comfortable to use and have a high tolerance for daily wear and tear. The designs are rooted in an understanding of the needs of the user and strive to optimize the user experience as much as possible.
