- 12.1: Is Economics Important?
- This page contrasts personal financial choices with engineering financial decisions, introducing engineering economics as the framework used to balance cost, safety, and technical performance when evaluating real-world solutions.
- 12.2: Trade-offs
- This page uses a car purchase example to illustrate how financing, interest, and lost opportunity costs affect major spending decisions in both personal finance and engineering projects.
- 12.3: The Time Value of Money
- This page explains the Time Value of Money, demonstrating how simple and compound interest work and comparing how different compounding frequencies impact total financial growth over time.
- 12.4: Break Even Point
- This page defines the Break Even Point (BEP) in engineering economics and provides a mathematical model and step-by-step example to calculate when product sales fully recover initial investment costs.
- 12.5: Return on Investment
- This page defines Return on Investment (ROI) in engineering economics, provides formulas and a worked example for calculating annual ROI, outlines industry sector benchmarks, and explains how ROI guides project evaluation.
- 12.6: Summary
- This page lists core engineering economics concepts, summarizing financial decision-making frameworks, the Time Value of Money, interest compounding dynamics, Break-Even Point analysis, and Return on Investment metrics.
- 12.7: End-of-Chapter Assignments
- This page contains engineering economics problems involving time value of money, break even points, and return on investments.
