Abstract
In this paper, the orientation of a long rectangular bar in still water was investigated. The inclination angle of the bar was analyzed based on Archimedes' principle and the conditions of the existence of a solution. The inclination angle φ of the bar are given by the widthlheight ratio of a section of a and the specific gravity a of the bar. The orientation of the rectangular bar is classified on the map of α-σ. The orientation of a long rectangular bar is illustrated.
