This textbook is intended for students from speciality "Ship Machines and Mechanisms" in Nikola Vaptsarov Naval Academy for the discipline "Mechanics of Materials". It is not a detailed and comprehensive course for this discipline. The author aims to present the content in the most accessible and illustrated way. Besides, all examples aim to show the applicability of the theory in the future work of students, namely the operation of ship machinery and mechanisms. The knowledge acquired in this discipline is a theoretical foundation in the study of special disciplines.

Seaworthiness is the ability of vessels to sail as well as to remain stable on the water surface, to provide normal living conditions for the people and safe ship operation which does not endanger the environment. The Maintain of Seaworthiness of the Ship Teaching Guide covers the IMO 7.03 and 7.04 Model Courses for the education of ship officers.
The course to Technical Mechanics is designed for students of non-mechanic specialties studying shortened course to mechanics. It considers the basic issues of “Theoretical Mechanics” and “Mechanics of Materials” according to syllabuses for specialties “Navigation” and “Exploitation Fleet and Ports” and other non-mechanical specialties.
The Machine Elements handbook is intended for marine engineers. It is based on the IMO Model Course 7.04 “Officer in charge of an Engineering Watch”. It is mostly practically oriented.
