Machine elements deals with traditional mechanical functions and structures of the elements that constitute primary functions of machines, e.g. bearings, transmissions, brakes, gears, joints, etc. Function, design and analysis of individual machine elements and assembled machine elements constitute key teaching and research areas. The subject is traditionally based, among other things, on mechanics, strength of materials and materials science in addition to the necessary basic technical sciences. Industrial development in recent decades has driven increasingly complex and high performance products, combining mechanical functions with electrical and digital solutions based on measurement and control technology, artificial intelligence and machine learning. Right now the division is focussed on non-exhaust from wear of components and high performing gears.
