This result of applying a force on a point that moves in space and a formula is defined by T = F x e (force x space). According to the formula, if not movement there is no work; However, if we do a static work, there will be fatigue that requires contraction - permanent and imperceptible relaxation to the human eye, which in the strict sense makes it a dynamic work.

Abstract
Developing useful objects for a functional reeducation of senior citizens persons about the basic activities of daily living must be conceptualized considering theories, techniques, and approaches in methodology, based on ecologically bearable structures, economically viable, and socially equitable. Consequently, the present chapter has the objective to state the criteria and strategies of a sustainable design, from a detailed study of applicability of 1) user-product interaction, observation, understanding, dimensional relationship, and evaluation; 2) creative process, identification, ideation, definition, prototypes, evaluation, and structuration; 3) technical specifications, structure, sustainability, ergonomics, aesthetics, and evaluation; 4) manufacture method, sustainability, production method, life cycle, capital assets, official norms, and optimization. A contextual and conceptual analysis is proposed for the beginning, development, and conclusion of the projects so as to reestablish the relationship between natural processes and human activity.
