While M.D. Dayal is a renowned author of engineering textbooks, such as Strength of Materials and Engineering Mechanics
, he has not written a literal "story" book in the fictional sense.
The phrase "story on strength of materials" in this context typically refers to the conceptual narrative or historical development of the subject provided in his textbooks. Key Narrative Elements in M.D. Dayal's Books
In his texts, Dayal often structures the "story" of the subject as a progression from rigid bodies to deformable bodies: The Transition: He explains that while Engineering Mechanics deals with rigid bodies (no deformation), Strength of Materials
(or Mechanics of Deformable Bodies) acknowledges that all real structures deform under load.
The Conflict: Engineering structures are subjected to loads that threaten to cause failure or fracture. The "story" of the material is its struggle to stay within acceptable deformation limits while remaining strong, stiff, and stable.
Human Element: Dayal's prefaces sometimes touch on the "human drama" of science—the mistakes, controversies, and perseverance of researchers that led to our current understanding of material behavior. Accessing the Material
