C) 30 minutes
D) 60 minutes

Answer 1

D

Question 2

Discuss what a designer must consider as a part is planned.

Answer 2

As a part is planned, the designer must consider
(1) its function either as a separate unit or as a part that must move in a fixed position in relation to other parts,
(2) the operations required to produce the part,
(3) the material to be used,
(4) the quantity to be produced, and
(5) the cost. Each of these factors influences the degree of accuracy to which a part is machined.
