The book that an engineer uses to formally document in chronological order all of the work that is associated with a design project is called a(n)

• Engineering diary

• none of these

• Engineering design notebook

• Engineering novel

A third-class lever is best described as

• The effort and resistance forces are on the same side of the fulcrum

• The effort and resistance forces are on the same side of the fulcrum and the effort force is closer to the fulcrum

• The effort and resistance forces are on the same side of the fulcrum and the resistance force is closer to the fulcrum

• The effort and resistance forces are on opposite sides of the fulcrum and the effort force is closer to the fulcrum

The diagram illustrates which class of lever

• Class 1

• Class 2

• Class 3

• Class 4

Brainstorming is an important step when starting a design project because

• It’s important to create multiple initial ideas

• All design team members have ideas that may contribute

• The initial ideas may provide the impetus for improved design ideas

• All of the above
