KTU S3  Mechanics Of Solids MOS Notes Mech | MET201 2019

Mechanics Of Solids MOS
is one of the most important subjects for anyone pursuing a degree or career in Mechanical Engineering. It is also one of the subjects in which students often struggle the most. The main reason for this is the vast amount of theoretical knowledge and the mathematical calculations required to do well in this subject.

The course is designed to provide students with a solid understanding of the behaviour of materials under various loading conditions. The course covers stress, strain, elasticity, fracture, and fatigue. The notes for this course are designed to be easy to understand and provide a comprehensive overview of the material. The notes are based on the 2019 scheme and are up to date with the latest syllabus.
