1 | Components having more details can easily produced by: (a) extrusion (b) hot rolling (c) casting (d) none of them |
2 | The bottom half of the casting is termed as: (a) bottom (b) cope (c) drag (d) end |
3 | Cores are used to: (a) remove pattern easily (b) increase strength of mould (c) make desired recess in casting (d) uniform distribution of molten metal |
4 | The top half of a casting used in moulding is termed: (a) drag (b) top (c) set (d) cope |
5 | A sprue pin is used in casting to: (a) hold the cast together (b) form the hole for the molten metal (c) make small holes to allow the gas to escape (d) smooth the face of the mould |
