संरचनाओं के प्लास्टिक विश्लेषण (plastic analysis) में, एक ठोस आयताकार अनुप्रस्थ काट (rectangular cross-section) के लिए आकार गुणांक (shape factor) कितना होता है?

A cantilever beam of length L and a cross-section with shape factor s carries a uniformly distributed load over its entire span. The ratio of the length of the plastic zone (Lp) to the total length (L), when the maximum bending moment equals the plastic moment MP, is given by:

In the analysis of structures using plastic theory, which of the following conditions must be satisfied simultaneously for a complete collapse mechanism solution?
