prismatic beam造句怎么写

Based on the theory of the bending of non-prismatic beam, the paper has derived a rigidity matrix and the equivalent node load of the rigid-frame element with variable sections.

These formulas give us the stress and strain in a prismatic beam when it subjected to pure bending.

The traditional solvent of static and dynamic problems for stepped prismatic beams is to set up ordinary differential equation in each step and answer it respectively.
