This would draw thestudents' attention to the wide variety of applications of fluid mechanics in our lives, andhenceforth the importance of learning the material with a spirit of enthusiasm.Upon collecting all ideas, the topics are classified into categories of fluid mechanics fields.Thereby, one of the first things introduced would be the difference between hydrostatics andfluid mechanics.

The team scrutinized the construction plans and identifiedthe corresponding wood members to size and cut for use later in the project. Based on ourprevious material take-off list, we were provided with just enough wood to complete the project,so a close attention to detail was necessary. The old saying, “measure twice, cut once” wassomething we all put into practice. The design process was greatly influenced by the previousproject at Maroon Bells; however, Maroon Bells was considered a designated wilderness area,which meant no mechanized equipment or power tools could be used in the vicinity
