The term that describes the reduction of weight while maintaining strength is known as optimization. In mechanical design, optimization involves evaluating various design parameters to achieve the best performance within given constraints. This process often includes minimizing weight without compromising the structural integrity or load-carrying capacity of a component.

Through optimization, engineers use mathematical models and simulations to analyze material usage and design geometries, aiming to achieve a balance between minimizing mass and ensuring safety and functionality. This concept is particularly important in industries such as aerospace and automotive, where weight reduction can lead to improved fuel efficiency and performance, but maintaining the necessary strength to withstand operational loads is equally crucial.

Fatigue refers to the weakening of materials over time due to cyclic loading, which is not directly related to the concept of weight reduction and strength. Stiffness describes a material's resistance to deformation under load, and while it is important for structural performance, it does not inherently relate to weight optimization. Load bearing is a broader term that refers to the ability to support weight or loads, but it does not specifically address the goal of reducing weight while maintaining strength.
