1.1 What are the differences between primary, secondary, and tertiary industries? Give an example
ss ss ss ss ss ss ss ss ss ss ss ss
of each category.
ss ss ss
Answer. A primary industry is one that cultivates and exploits natural resources, such as
ss ss ss ss ss ss ss ss ss ss ss ss ss
agriculture or mining. A secondary industry takes the outputs of primary industries
s s s s s s s s s s s s s s s s s s s s s s s s
and converts them to consumer and capital goods. Examples of secondary industries are textiles
s s ss ss ss ss ss ss ss ss ss ss ss ss ss
and electronics. A tertiary industry is in the service sector of the economy. Examples of tertiary
ss ss ss ss ss ss ss ss ss ss ss ss ss ss ss ss
industries are banking and education.

1.2 What is a capital good? Provide an example.
ss ss ss ss ss ss ss
Answer. Capital goods are those purchased by companies to produce goods or provide services.
ss ss ss ss ss ss ss ss ss ss ss ss ss
Examples of capital goods are aircraft and construction equipment.
ss ss ss ss ss ss ss ss ss
1.3 How are product variety and production quantity related when comparing typical factories?
ss ss ss ss ss ss ss ss ss ss ss
Answer. Generally production quantity is inversely related to product variety. A
s s ss ss ss s s ss ss ss s s s s
factory that produces a large variety of products will produce a smaller quantity of each.
ss ss ss ss ss ss ss ss ss ss ss ss ss ss ss
A company that produces a single product will produce a large quantity.
ss s s ss ss ss ss ss ss ss ss ss ss
1.4 Define manufacturing capability. ss ss
Answer. Manufacturing capability refers to the technical and physical limitations of a
ss ss ss ss ss ss ss ss ss ss ss
manufacturing firm and each of its plants. Three categories of capability mentioned in the
ss ss ss ss ss ss s s s s ss s s ss ss ss ss
text are
ss ss
(1) technological processing capability, (2) physical size and weight, and (3) production capacity.
ss ss ss ss ss ss ss ss ss ss ss ss
1.5 Name the three basic categories of materials.
ss ss ss ss ss s s
Answer. The three basic categories of engineering materials are (1) metals, (2) ceramics, and (3)
ss ss ss ss ss ss ss ss ss ss ss ss ss ss
polymers. A fourth category, composites, is a non-homogeneous mixture of the other types and
ss ss ss ss ss ss ss ss ss ss ss ss ss ss
therefore is not a basic category.
ss ss ss ss ss ss
1.6 How does a shaping process differ from a surface processing operation?
ss ss ss ss s s ss ss ss ss ss
Answer. A shaping process changes the geometry of the work material (machining or forging). A
ss ss ss ss ss ss ss ss ss ss ss ss ss ss
surface processing operation does not alter the geometry, but instead alters surface of the work
ss ss ss ss ss ss ss ss ss ss ss ss ss ss ss
(painting or plating).

1.7 What are two subclasses of assembly processes? Provide an example process for each subclass.
ss ss ss ss ss ss ss ss ss ss ss ss ss
Answer. The two subclasses of assembly processes are (1) permanent joining and (2) mechanical
ss ss ss ss ss ss ss ss ss ss ss ss ss
fastening. Examples of permanent joining include welding or adhesive bonding. Examples of
ss ss ss ss ss ss ss ss ss ss ss ss
mechanical fastening include threaded fasteners, such as nuts and bolts, and rivets.
ss s s ss ss ss ss s s s s ss ss ss ss
1.8 Define batch production and describe why it is often used for medium-quantity
ss ss ss ss ss ss ss ss ss ss ss
production products.
ss ss
Answer. Batch production is where groups, lots, or batches or materials or parts are processed
ss ss ss ss ss ss ss ss ss ss ss ss ss ss
s together through the manufacturing operations. All units in the batch are processed at a given
s ss ss ss ss ss ss ss ss ss ss ss ss ss ss
station before the group proceeds to the next station. In a medium or low quantity production
s s ss ss ss ss ss ss ss ss ss ss ss ss ss ss ss
s situation, the same machines are used to produce many types of products. Whenever a
s ss ss ss ss ss ss ss ss ss ss ss ss ss
machine switches from one product to another, a changeover occurs. The
ss s s s s s s s s s s s s s s s s s s ss
changeover requires the machine setup to be torn down and set up for the new product.
