Unit I
Engineering Mechanics and Strength of Materials (Basics): Types of forces and their effects; concept of stress and strain; beams — types of loads (point load, UDL), engineering materials — metals, polymers, ceramics, composites (properties and uses). Applications: frame of a laptop/server rack, load on a tower antenna, material selection for a robot arm, chassis of an electric vehicle.
Unit II
Thermodynamics and Heat Transfer Basics: System and surroundings; laws of thermodynamics; heat transfer — conduction, convection, radiation. Applications: cooling fan and heat sink in a computer processor, AC in a server room/data centre, EV battery thermal management.
Unit III
Machine Elements and Power Transmission: Fasteners — bolts, screws, keys (types and use); shafts and couplings — rigid and flexible; bearings — ball bearing and roller bearing; belts and chains. Applications: gear train in a robotic joint, belt drive in a 3D printer, ball bearings in drone motor.
