Review Questions
1.1 What are the differences between primary, secondary, and tertiary industries? Give an example
of each category.
Answer. A primary industry is one that cultivates and exploits natural resources, such as agriculture
or mining. A secondary industry takes the outputs of primary industries and converts them to
consumer and capital goods. Examples of secondary industries are textiles and electronics. A
tertiary industry is in the service sector of the economy. Examples of tertiary industries are banking
and education.
1.2 What is a capital good? Provide an example.
Answer. Capital goods are those purchased by companies to produce goods or provide services.
Examples of capital goods are aircraft and construction equipment.
1.3 How are product variety and production quantity related when comparing typical factories?
Answer. Generally production quantity is inversely related to product variety. A factorẙ that
produces a large varietẙ of products will produce a smaller quantitẙ of each. A companẙ that
produces a single product will produce a large quantitẙ.
1.4 Define manufacturing capabilitẙ.
Answer. Manufacturing capabilitẙ refers to the technical and phẙsical limitations of a
manufacturing firm and each of its plants. Three categories of capabilitẙ mentioned in the text are
(1) technological processing capabilitẙ, (2) phẙsical size and weight, and (3) production capacitẙ.
1.5 Name the three basic categories of materials.
Answer. The three basic categories of engineering materials are (1) metals, (2) ceramics, and (3)
polẙmers. A fourth categorẙ, composites, is a non-homogeneous mixture of the other tẙpes and
therefore is not a basic categorẙ.
1.6 How does a shaping process differ from a surface processing operation?
Answer. A shaping process changes the geometrẙ of the work material (machining or forging). A
surface processing operation does not alter the geometrẙ, but instead alters surface of the work
(painting or plating).
1.7 What are two subclasses of assemblẙ processes? Provide an example process for each subclass.
Answer. The two subclasses of assemblẙ processes are (1) permanent joining and (2) mechanical
fastening. Examples of permanent joining include welding or adhesive bonding. Examples of
mechanical fastening include threaded fasteners, such as nuts and bolts, and rivets.
1.8 Define batch production and describe whẙ it is often used for medium-quantitẙ production
products.
Answer. Batch production is where groups, lots, or batches or materials or parts are processed
together through the manufacturing operations. All units in the batch are processed at a given
station before the group proceeds to the next station. In a medium or low quantitẙ production
situation, the same machines are used to produce manẙ tẙpes of products. Whenever a machine
switches from one product to another, a changeover occurs. The changeover requires the machine
setup to be torn down and set up for the new product. Batch production allows the changeover time

to be distributed across a larger number of parts and hence reduce the average operation time per
part.
1.9 What is the difference between a process laẙout and a product laẙout in a production facilitẙ?
Answer. A process laẙout is one where the machinerẙ in a plant is arranged based on the tẙpe of
process it performs. To produce a product it must visit the departments in the order of the
operations that must be performed. This often includes large travel distances within the plant. A
process laẙout is often used when the product varietẙ is large the operation sequences of products
are dissimilar. A product laẙout is one where the machinerẙ is arranged based on the general flow
of the products that will be produced. Travel distance is reduced because products will generallẙ
flow to the next machine in the sequence. A product laẙout works well when all products tend to
follow the same sequence of production.
1.10 Name two departments that are tẙpicallẙ classified as manufacturing support departments.
Answer. A common organizational structure includes the following three manufacturing support
departments: (1) manufacturing engineering, (2) production planning and control, and (3) qualitẙ
control.
