The Saoraja Lapinceng traditional house in Barru Regency has social, cultural and religious values. In addition, this traditional house has a physical value, namely the concept of rigid body equilibrium. The research objective is to analyze the concept of rigid body equilibrium at the Saoraja Lapinceng traditional house. The research method used is the traditional review. Data obtained from journals, books, and websites that are relevant to this research, which are then reduced, presented, verified, and conclusions drawn. Based on the results of the research, it is obtained: (1) The support poles (Aliri) in the main building are rectangular in shape following the Bugis Sulapa Appa philosophy and an odd number with the total force and torque acting on the poles equal to zero, the support poles cause the main building to not move (balance). (2) The foundation of the umpak (Pallangga) is rectangular and has an odd number of values of life and death for the Buginese community where Pallangga functions to make Aliri immobile (balance). (3) Attic support (Pattolo') following the width of the house gives Aliri and Arateng a style which is the same as the force received by Pallangga, thereby helping Aliri to balance the main building. (4) Floor support (Arateng) functions to connect Aliri with other Aliri in the long direction of the house so that the force and torque to the main building body are equal to zero (balance). (5) The stairs (Addengeng) are made with a slope of 30 to 45 from Aliri, so that the vertical force from the floor and the horizontal force from the wall, balances the ladder when given Addengeng's load. © 2021 Published under licence by IOP Publishing Ltd.
