Abstract
A method of representing the static demands upon forceful exertion of a task, and limitations of performance due to friction, as environmental statements on a chart called the Postural Stability Diagram (PSD), is given. Examples of the technique are drawn from the tasks of handling objects on shelves while standing on a stool, and of supporting a trolley on an incline. When the personal capacity to exert force (the subject of a preceding paper) is-depicted on the same chart as the task-demands, the degree of match between the person and task may be considered by a procedure called PSD analysis. The method is intended for use by task-designers and safety engineers as soon as anthropometric data becomes available.This publication has 1 reference indexed in Scilit:
