The engineering marvel of the jet engine. How the turbojet, ramjet, and scramjet achieve their incredible top speeds.
Student design engineers often require a \"cookbook\" approach to solving certain problems in mechanical engineering. With this focus on providing simplified information that is easy to retrieve, retired mechanical design engineer Keith L. Richards has written Design Engineer's Handbook. This book conveys the author's insights from his decades of experience in fields ranging from machine tools to aerospace. Sharing the vast knowledge and experience that has served him well in his own career, this book is specifically aimed at the student design engineer who has left full- or part-time academic studies and requires a handy reference handbook to use in practice. Full of material often left out of many academic references, this book includes important in-depth coverage of key topics, such as: Effects of fatigue and fracture in catastrophic failures Lugs and shear pins Helical compression springs Thick-walled or compound cylinders Cam and follower design Beams and torsion Limits and fits and gear systems Use of Mohr's circle in both analytical and experimental stress analysis This guide has been written not to replace established primary reference books but to provide a secondary handbook that gives student designers additional guidance. Helping readers determine the most efficiently designed and cost-effective solutions to a variety of engineering problems, this book offers a wealth of tables, graphs, and detailed design examples that will benefit new mechanical engineers from all walks.

We are a Leader In Me School and talk a lot about using the 7 Habits of Happy Kids in our everyday lives. I love the idea of encouraging kids to act as leaders in the classroom and beyond. What I have noticed, however, is that sometimes "leadership" comes off as "bossypants" and that is not the route we want to take! I know you've probably heard of Sheryl Sandberg (of Facebook fame) and her campaign to end the word "bossy" (read or listen to an NPR story HERE), but I was hesitant to come straight out and use that word in our class. Instead, I wanted them to think on terms of "boss" and "leader" to recognize the differences between the two and to think about their own language choices in the classroom, in small groups, on their sports teams, and more. We first looked at this picture and talked about what we noticed: (source) This led to some discussion about leadership versus boss behavior. While the kids were discussing, I was passing out example cards to their table spots. Before I dismissed them, I shared this leadership quote from John Quincy Adams: They were then given instructions about our activity. I had printed example cards on two colors: blue for boss and green for leader (although they didn't know that yet) and they needed to read their card and find someone with an opposite color card and opposite example (good time to incorporate the word antonym, too!). I dismissed them to their tables and first had them converse with students in their table group to ensure they understood the word or phrase on their card. When they gave me the thumbs up, I told them to find their match and them meet to discuss why they went together and be able to give examples. We then began assembling our Anchor Chart. Each pair would come to the front of the class and would explain which card was descriptive of a "boss" and which was descriptive of a "leader" and why. They gave examples and I elicited a lot of help from the classroom for additional examples and language that both a boss and leader may use during that example. I would tape the cards to the Anchor Chart and we continued through each pair. There were two groups of three (with two leaders to one boss) and that worked out perfectly with my class (definitely feel free to adjust if you have lower numbers). Our completed anchor chart looked like: It was so powerful to see how often kids may think they are helping, but instead find themselves on the "boss" side of the chart instead of the "leader." I know several of the examples are repetitive, but we really talked through these and used examples from our own lives to recount when using "leader" words and language set us up for success. I also explained the "me vs. you" mentality of bosses versus the "we and us" mentality of leaders. Overall, it was a very powerful lesson and I look forward to referring back to this Anchor Chart this year, especially when "bossypants" behavior leads to conflict. I think these concrete examples can help guide the naturally strong leaders in my class to make better language decisions that can help grow them as leaders and really inspire others, just like the Adams quote! If you'd like a copy of these cards and quote, you can download this as a *freebie* HERE. How do you address bossy vs. leader behavior in your class? Share in the comments, I would love to build on this lesson!
