For all other mechanical 5th sem syllabus for diploma m scheme TNDTE, you can visit Diploma in Mechanical Engineering 5th Sem Syllabus M Scheme. The detail syllabus for design of machine elements is as follows.
Rationale:
The main objective of Machine Design is to create new and better machine components to improve the existing one. A mechanical engineer should have thorough knowledge of design of machine elements to avoid the failure of machines or components.
Objectives:
- Design riveted joints, welded joints, sleeve and cotter joint and knuckle joint.
- Design eye bolts, cylinder cover studs.
- Design shafts, keys and couplings required for power transmission.
- Compare the different types of couplings.
- Design flat and V-belt for power transmission.
- Study the various types of bearings and their applications.
- Design journal bearings.
- Design spur gear used for power transmission.
- Design hand lever, foot lever and cranked lever.

Unit 2
Design Of Shafts, Keys And Couplings
Shafts:
Design of shafts subjected to – twisting moment – bending moment – combined twisting and bending moments – fluctuating loads – design of shafts based on rigidity.
Keys:
Types of keys – design of sunk keys only – Effect of keyways on shaft-problems.
Couplings:
Requirements of good couplings – types – design of – rigid protected type flange couplings – marine couplings – pin type flexible coupling (Description only).
Unit 3
Design Of Flat Belts And V-Belts
Flat Belts:
Types of belts – materials for belt — types of belt drives -Speed ratio – effect of slip – length of flat belts -Tension Ratio T1/T2=e^e- centrifugal tension – power transmitted – condition for maximum power – transmission – Initial Tension – problems – design procedure of flat belts – design of flat belt based on manufacturer’s data only – problems.
V-Belts:
V-belt drive – comparison with flat belt drive – designation of V-belts – length of belt – power transmitted – Design of V-belt using manufacturer’s data only – Problem.
