Unit 3.2 Functional Analysis

Concepts 1. Engineers perform reverse engineering on products to study their visual, functional, and structural qualities. 2. Through observation and analysis, a product’s function can be divided into a sequence of operations. 3. Products operate as systems, with identifiable inputs and outputs.

Unit 3.2 Functional Analysis Black Box Model A graphic system ’ s illustration referred to as a Black Box because the internal components or process is deemed unknown, or mysterious. Compound Machine A mechanism that consists of two or more simple machines. Function The kind of action or activity proper to a person, thing, or institution; the purpose for which something is designed or exists; role. Hypothesis 1. An assumption made on the basis of limited evidence as a starting point for further investigation. 2. A proposed explanation for an observation. Hypothesis is an educated guess which forms a basis for a test. Input Something put into a system, such as resources, in order to achieve a result. Mechanism An assembly of moving parts completing a complete functional motion. Observation The act or instance of noticing or perceiving. Output The results of the operation of any system. Process 1. Human activities used to create, invent, design, transform, produce, control, maintain, and use products or systems; 2. A systematic sequence of actions that combines resources to produce an output. Reverse Engineering The process of taking something apart and analyzing its workings in detail, usually with the intention to understand function, prepare documentation, electronic data, or construct a new or improved device or program, without actually copying from the original. System A group of interacting, interrelated, or interdependent elements or parts that function together as a whole to accomplish a goal.

Essential Questions 1. What is the purpose of reverse engineering? 2. What is the difference between a product’s visual and functional qualities?
