1. a) Explain the manufacturing aspects of design. b) List the different design considerations. c) How ductility can be estimated from tensile test data? d) Explain creep curve. e) Explain factor of safety used in design. 05x02 10 2. A socket and spigot cotter joint transmits an axial load of 60 KN. Design the spigot and cotter (Cotter must be weaker by 30%). 3. A machine component is subjected to following stresses: o--10 MPa, oy=-60 MPa, txy-30 MPa. Material is plain carbon steel having yield strength=320 MPa, tensile strength=550 MPa and Poisson's ratio 0.3, E-210 GPa. Calculate the factor of safety using Maximum normal stress, Distortion energy and Maximum normal strain theories. 10 ---X-----
