Act for each employer or client as faithful agents or trustees.

Fundamental Canon 5

Avoid deceptive acts.

Fundamental Canon 6

Functional Decomposition

Breaking down a design into its parts

Function Requirement

What the system should do, the tasks it should do

What are the three E’s

Environment, Equity, and Economy

Economy (Profit)

Economically viable practices that are socially and environmentally responsible

Environment (Planet)

Efficient management of natural resources to ensure preservation for future needs

Equity (People)

Strengthening the cohesion and stability of populations and their development

Systems Thinking

Human-made designs and activities rely upon, respond to, and are embedded within ecological, physical, climate, economic and social systems

Sustainability

Meeting the needs of the present without compromising the ability of future generations to meet their own needs

Machine Shop Safety Rules

-Safety glasses

-Closed toe shoes

-No food or drinks

-Wash eyes for 15 minutes if chemicals get in them

-Do not machines you do mot know how they work

-No loose hair, loose clothes, or jewlery

Pugh Matrix

Uses design requirements to decide which design is the best to do (creates a quantitative value to each design)

ABC Matrix

Each row (ABC) represents a different functional requirement & each column represents a different concept to fufill that requirement

Ohm’s Law

V (Voltage) = I (current) x R (Resistance)

Amps to Milliamps

Multiple Amps by 1000

Milliampere to Ampere

Divide milliamp by 1000

What current do you use for Ohm’s Law

Use amps (UNLESS YOU ALSO USE KILOHMS)

Ohms and Kiloohms

Ohms —> Kilo-ohms (divide by 1000)

Kilo-ohms —> Ohms (Multiple by 1000)

In a series circuit, all of the resistors

equal the total voltage

Current (I) calculation

total voltage/total resistor values

How to calculate each resistors’ voltage

Current (I) x Resistor value (prefereably use kilo-ohms)

Voltage units

V (Volts)

Current Units

Amps (A) or milli-amps (mA)

Resistor Units

ohms (Ω) or milli-ohms (mΩ)
