Introduction
The Problem & Career Focus: You are a marine engineer challenged with designing a prototype of a cargo ship. You will use this prototype to conduct an experiment to determine how freshwater and saltwater affect a cargo ship’s buoyancy. You will use your finding to advise the captain of whether or not he should accept the job offer. |
