- CO2: List the functions and uses of machine elements used in mechanical systems.
- CO3: Apply codes and standards in the design of machine elements and select an element based on the Manufacturer’s catalogue.
- CO4: Analyse the performance and failure modes of mechanical components subjected to combined loading and fatigue loading using the concepts of theories of failure.
- CO5: Demonstrate the application of engineering design tools to the design of machine components like shafts, couplings, power screws, fasteners, welded and riveted joints.
- CO6: Understand the art of working in a team.
Question Paper Pattern:
- The question paper will have ten full questions carrying equal marks.
- Each full question will be for 20 marks.
- There will be two full questions (with a maximum of four sub- questions) from each module.
- Each full question will have sub- question covering all the topics under a module.
- The students will have to answer five full questions, selecting one full question from each module.
