b) Selection of materials, Basic criteria of selection of material, their
designation, mechanical properties of those materials in brief.
c) Study of Stress concentration, factor of safety under different loading
conditions,
3. Basic Design:
Design for static loading, design for variable loading for both limited and
unlimited life, concept of fatigue and endurance strength.
4. Design of fasteners:
a) RIVETS: Desing of rivets for boiler joints, lozenge joints (uniform strength
joint), eccentrically loaded riveted joints
b) BOLTS: Understanding the various stresses/ failure in bolted joints, design
of cylindrical covers, basic and eccentrically loaded bolts
c) WELDS: Design for various loading conditions in torsion, shear or direct
load, eccentrically loaded welded joints.
d) MISCELLENEOUS: Design of spigot and socket cotter joint, Gib and
Cotter joint and knuckle joint.
5. Design of Transmission Shaft
Design of both solid and hollow shafts for transmission of torque, bending
moments and axial forces, Design of shaft for critically speed, Design of shaft
for rigidity and Design of stepped shafts for assembly
6. Design of Keys and Couplings:
Design of sunk keys under crushing and shearing, design of splines, design of
sleeve and solid muff coupling, clamp or compression coupling, rigid and
flexible flange coupling, design of universal joint
7. Lever design:
