• Unit 1.Introduction: Objective, scope and outcome of the course.

  
  Unit 2. Materials: Mechanical Properties and IS coding of various materials,Selection of material from properties and economic aspects.Manufacturing Considerations in Design:Standardization,
  Interchangeability, limits, fits tolerances and surface roughness, BIS
  codes, Design consideration for cast, forged and machined parts. Design for assembly.

  
  Unit 3. Design for Strength: Modes of failure, Strength and Stiffness considerations,Allowable stresses, factor of safety, Stress concentration: causes and mitigation, fatigue failures.
  Design of Members subjected to direct stress: pin, cotter and keyed joints.

  
  Unit 4. Design of Members in Bending: Beams, levers and laminated springs.Design for stiffness of beam: Use of maximum deflection formula for various end conditions for beam design
   

  Unit 5. Design of Members in Torsion Shaft and Keys: Design for strength,rigidity. Solid and hollow shafts. Shafts under combined loading. Sunk keys.
  Couplings: Design of muff coupling, flanged couplings: rigid and flexible
   

  Unit 6. Design of Threaded fasteners: Bolt of uniform strength, Preloading of bolts: Effect of initial tension and applied loads, Eccentric loading Power screws like lead screw, screw jack
  Design of members which are curved like crane hook, body of Cclamp,machine frame etc.
