Course Outcomes:
On completion of the course, the student will be able to:
- Explain types of mechanisms, fasteners and welded joints and identify them for specific applications
- Apply the basic theory of design of shafts and keys for mechanical power transmission
- Explain the applicability of cams, flywheels and governors in the design of mechanical systems
- Describe the various types of mechanical power transmission devices and their selection on specific applications
Module 1:
General Considerations in Machine Design; Design stress, working stress and factor of safety Simple mechanisms: Definition and explanation of the terms- Kinematic link or element, Kinematic pair, kinematic chain, mechanism, inversion of mechanism; types of constrained motions, classification of kinematic pairs; types of kinematic chain-four bar chain, single slider crank chain, double slider crank chain Fastener: types of fastener -permanent and temporary Permanent fastener- types; Welded joints: Types of welded joints-Lap joint or fillet joint and butt joint; weld terms- leg or size of the fillet weld, throat thickness; strength of axially loaded symmetrical welded sections- transverse fillet weld, parallel fillet weld,
combination of transverse and parallel welds (Simple numerical problems) Riveted joints: Types, lap joint-single riveted, double riveted (chain and zigzag), butt joint – single cover single riveted, double cover single riveted (no numerical problems) Temporary fastener- types; Advantages and dis advantages of threaded joints; forms of thread, Designation and nomenclature of screw thread
