Explanation / Answer

Q1)

a) True

b) False

primary manufacturing processes are:

Casting, Forming, such as Forging, Rolling, Extrusion, etc
Joining, such as Welding, Soldering, etc.

secondary manufacturing processes are:

Machining
Surface working, such as Heat Treatment, Coating, etc

Discrete manufacturing is the production of distinct items. But continuous manufacturing is a continuous production process

c) False

Stress is a tensor which has both magnitude and direction. Pressure is a scalar, only has magnitude.

d) False

Ultimate stress is the maximum stress that occur after yielding or plastic deformation

e) False, they are dependent on material and loading conditions

f) True

g) True

h) True

Q2)

a) None of the above, they are not welding processes, they use to join metals by using filler metal without affecting(melting) the base metal.

b) sheet metal processes

c) Rupture strength, after this point the material will break or fail

d) Foundries.  A foundry is a factory that produces metal castings

e) Turning

Turning is a material removal process which is used to remove material from cylimdrical surface of the workpiece.

Facing is one of the turning processes in which material is removed from circular portion of cylindrical workpiece.
