Solve the six equations for the six unknowns. Please check out the playlist containing updated videos on the same topic: 2015 Engineering. Further equations can be obtained by summing the moments about other points, but they will not be independent of the first moment equations.īecause there are not more than six independent scalar equations, it is not possible to solve for more than six unknowns. Apply the equilibrium equations for a rigid body in equilibrium under a three-dimensional system of forces. Statics Lecture 21: Rigid Body Equilibrium - 3D supports. Note that the sum of the moments can be evaluated about any point. These also represent six independent scalar equations, Static Determinacy/Partial and Improper Constraints Static Indeterminacy: occurs when a system has more constraints than is necessary to hold the system in equilibrium (i.e., the system is overconstrained and thus has redundant reactions).

Keywords: Funicular polyhedral frames, concrete spatial structure, 3D graphic statics, form finding, prefabricated concrete construction, equilibrium of polyhedral frames. Using rectangular coordinates, these vector equations can be expanded into equilibrium of polyhedral frames (Rankine 22) and the methods of 3D graphical statics as the recent development of this principle. Equilibrium section, it was shown that the sum of all forces and the sum of all moments acting on a rigid body in equilibrium must be equal to zero, The course addresses the modeling and analysis of static equilibrium problems with an emphasis on real world engineering applications and problem solving.
