The main aim is to “see what is behind of the words” stress and strain in different types of geometries and load combinations and to understand what it means that stress is above yield limit in a tube for example. To see what are basic machine elements also. And finally, we will design basic machine elements for safe life using specific theoretical equations under loads and compare in some cases with some experimental rules. 

Course Description  

Stress Components, Mohr’s Circle, Triaxial Stress, Uniformly distributed stresses, Elastic strain, Free body diagrams, Shear and moment, Singularity Functions, Normal stresses in Flexure, Beams with asymmetrical Sections, Shear Stress in beams, Shear stresses in rectangular-section beams, Torsion, Stress concentration, Stresses in cylinders, Rotating rings, Press and shrink fits, Temperature effects, Curved Members in Flexure, Contact stresses, Screws, Fasteners, Mechanical Springs, Shafts, Axles, Spindles, Connections, Rolling Contact Bearings, Bearings. 

Expected Course Outcome

At the end of the semester, the students will have the ability: 

• To know what are basic machine components and operation of these.
• To propose specific machine components according to specific request
• to design using fail safe criteria
