The study material consists of 5 modules as per syllabus prescribed by Visvesvaraya Technological University. For mechanical engineering.It covers the basic knowledge about oscillation, shockwaves and elasticity. It highlights the concepts of physio- mechanical and thermoelectric properties of materials. This also provides the basic knowledge required to understand the cryogenics and material characterization. The concepts and working of an instrument in engineering application and enhances practical problem-solving skills.Authors acknowledge Dr. S P Basavaraju and faculties of Department of Physics, Vidyavardhaka College of Engineering for their valuable inputs.
