                    Abstract 
                        
                            Using the principle of analytical geometry, several properties of the space straight line are proved. Based on these properties, the equilibrium of general space force system is considered and its four new scalar-type equilibrium equations are derived which are equivalent to the vector-type necessary and sufficient conditions for equilibrium.
