MT320 DESIGN OF MACHINE ELEMENTS

To familiarize students various steps involved in the design Process and to make them understand the principles involved in evaluating the shape and dimensions of a component to satisfy functional and strength requirements. Course Outcomes: On completion of the course, the students would be able to: 1. designing the components against static loading. 2. designing the components against cyclic loading. 3. designing the fasteners like rivits, bolts and cotter joints. 4. designing power transmission shafts and couplings. UNIT–I: Steady Stresses and Variable Stresses in Machine Members: Introduction to the design process- factors influencing machine design, selection of materials based on mechanical properties – Direct, Bending and Torsional stress equations. UNIT – II: Design of Shafts and Couplings: Design of solid and hollow shafts based on strength, rigidity and critica
