1.3 Describe how the U.S. Bureau of Labor Statistics defines an engineer and an engineering technician (or engineering technologies) by reviewing the “field of degree” highlights for students and job seekers in the Occupational Outlook Handbook. Describe the difference between an engineer and a technician and provide a salary range for each (www.bls.gov/ooh/field-of-degree).Solution This answer should include the salaries for an engineer (~$95,000 USD-2022) and a technician (~$78,000 USD-2022). This may differ based on which type of engineer is chosen from the Occupational Outlook Handbook. Answers should include the job descriptions of each job and any notable differences. These differences may include the following: job clearance levels, pay scale differences, educational differences, etc.

1.4 The National Society of Professional Engineers (NSPE) has established a Code of Ethics for engineers. Look up and write down the six fundamental canons of the NSPE Code of Ethics.Solution 1)Hold paramount safety, health, and welfare of the public 2)Perform services only in areas of their competenc e 3)Issue public statements only in an objective and truthful manner 4)Act for each employer or clients as faithful agents or trustees 5)Avoid deceptive acts 6)Conduct themselves honorably, responsibly, ethically, and lawfully so as to enhance the honor, representation, and usefulness of the profession 1.5 Describe the problems with using an ancient human proportion–based measurement system if you were to build a horse-drawn carriage and you were to purchase parts for the carriage and horses from 12 different suppliers. You are also concerned about navigating under a bridge that is one fathom high that you must pass under to get between your work and your home.Solution Responses may include the following: The ancient method is outdated due to the form of measurement used. Measurements were based on human portions which can vary from person to person, leading to inconsistent measurements. A horse drawn carriage consists of moving parts that must all simultaneously move together; if each supplier sells parts measured to their own proportions, there could be sizing issues that do not allow the carriage to properly function. If the underpass is sized using unique measurements, it would offer another challenge. In short, if everything is uniquely sized with the proportions of the manufacturers, then there are no uniform universal measurements, making it difficult to produce anything.
