15 The operation illustrated in Figure is know (a) Hot forging (b) Cold drawing (c) Impact Extrusion (d) Squeeze Casting 16. The parts shown are best produced by (a) forging (b) rolling (ek hot extrusion (d) cold extrusion 17. Figure is a schematic illustration of a shearing die used for making washers. This die is known as: (a) compound die (b) transfer die (c) progressive die (d) washer die 18. The force required to punch the triangular hole (as shown in the figure) in a 2 mm thick sheet having tensile strength of 700 MPa is: 29400 N (b) 25400 KN (c) 32100 N (4) 2 MN 7 (Por) (30) (1) A 19. As the bend radius to sheet thickness (R/t) ratio decreases (a) The compressive stress on the outer fiber increases (b) The compressive stress on the outer fiber decreases (c) The tensile stress on the outer fiber increases (d) The compressive stress on the outer fiber decreases 20. As the length of bend increases, the state of stress at the outer fibers of the sheet: (a) changes from plane strain to plane stress (b) changes from plane-stress to plane-strain (c) remains uni-axial stress (4) none of the above T
