[The principles of the combined and simultaneous action of industrial factors]
Abstract:
The laws of the development of tension of the main systems and regulatory mechanisms of the organism of people working both under exposure to occupational factors altogether and to various combinations of ergometric indices of work. Joint action of unfavourable labour conditions (dust, industrial noise, insufficient lighting) and of working process factors (local muscular stress, hardness and tension of labour), as a rule, cause potentiation of unfavourable changes in the functional status of the organism. In the majority of occupational groups the factors studied predetermine in 76-96% of cases changes in the functional state of the major systems of the workers' organism.

Categories of Equilibrium
One of the categories of equilibrium is collinear equilibrium, which involves forces acting along a straight line. This type of equilibrium requires only one force equation in the direction of the forces, as the other equations are...
