Description
The engineering product (from screw to aircraft, from screw driver to bullet train, from bolt to space rovers, nut to space shuttle) needs to be designed perfectly for their reliable usage during applications. Each and every engineering product, whether small or huge is subjected to several external loads during operation, in order to withstand these loads for that these products mush be designed perfectly while keeping the economical aspect. Stress and strain is the perfect concept that is developed to study the behavior of the material/products when subjected to external loading. This course will describe about the basic concept of stress and strain. How this concept and knowledge is used to determine the analytical models for deformation, deflection, stress, and strain under uni axial load, bi-axial load and tri-axial load will be discussed. Moreover, the stress transformation through analytical tools and graphical methods (Mohr’s circle) will also be elaborated in order to equipped the learners with the broad knowledge and understandings from design point of view. Beams which are the basic components of mechanical and civil engineering are also of this course,and shear force diagrams, bending moment diagrams, beams deflection, critical stress determination and beam designing can be easily learnt. Moreover, this course also covers about torsion in shafts and the shear stress produced in shafts and how to use the torsion analytical tools for the designing of shafts etc.
