This course is the application of many advanced techniques that allow engineers to design machine components, mechanisms, predict failure and understand the physical properties of materials. This course will be beneficial in that it would allow students to apply the skills and techniques they have learned in the previous module of Mechanics of Materials-I. Methods for determining the stresses, strains and deformations produced by applied loads are presented. Engineering design concepts are integrated throughout the course. At the completion of the course, students will be able to analyze and design components and structural members subjected to tension, compression, torsion, bending and combined loads using fundamental concepts of stress, strain, elastic and inelastic behavior.
COURSE LEARNING OUTCOMES (CLO)
CLO-1: Analyze beam and shell type structures for safety in terms of both strength and deflection limits. (C4)
CLO-2: Evaluate and Compare different design options for practical engineering structures and select suitable materials and/or configurations for such structures. (C5)
CLO-3: Design a real life structure or component, putting skills gained in the course to actual use. (C6)
CLO-4: Explain the findings of the design project in the form of an original report. (A3)
