| Abstract: |
| Based on calculating the geometrical characteristic values of a triangle with a vertex on the coordinate origin,this paper suggests a regular method for calculating geometrical and mechanical characteristic values of sections for structural bodies in a shape of prism. The geometrical values include area, area moment and inert moment,while the mechanical charcteristic values include gravity,static moment and rotating inertia. Compared with the common method,this regular method has the advantages of a wide adaptability and the suitability to computation with computers |
| Key words: structural body in shape of prism,characteristic value,section |
