Mechanism Design And Analysis: Developing An Understanding Of Mechanism Motion Through Graphical Modeling, Andrew J. Hughes, Chris Merrill
Mechanism Design And Analysis: Developing An Understanding Of Mechanism Motion Through Graphical Modeling, Andrew J. Hughes, Chris Merrill
Educational Leadership & Technology Faculty Publications
The intention of this article is to provide Technology and Engineering Educators with foundational knowledge of mechanism design and analysis and the ability to develop middle and high school students' mechanism knowledge during practical hands-on learning activities in the STEM classroom. Technology and Engineering Educators' implementation of mechanism design and analysis could promote students' increased depth of mechanical knowledge and ability to apply this knowledge during engineering design challenges. In this article, the authors present an introduction to four-bar mechanism design and analysis using CAD software to produce graphical representations. After designing mechanisms graphical, students should be allowed to produce …
Method Of Joints: Theory And Practice Of Designing, Building, And Testing Trusses, Andrew J. Hughes, Chris Merrill
Method Of Joints: Theory And Practice Of Designing, Building, And Testing Trusses, Andrew J. Hughes, Chris Merrill
Educational Leadership & Technology Faculty Publications
The authors of this article, like many of us, are proponents of engineering education but are also proponents of shop skills, craftsmanship, technological literacy, and the tacit knowledge and skills developed through applying sound theories during practical hands-on learning. The authors believe that engineering is an important aspect of our discipline, but so are the application of thinking, tool skills, measurement, geometric construction, manufacturing, instrumentation, testing and analysis, mathematical and scientific theories, and many other hands-on, minds-on skillsets that all need to maintain association with our discipline. As the authors are proponents for engineering education that is done well, they …
Concrete Beam Design: Pouring The Foundation To Engineering In T&E Classrooms, Andrew J. Hughes, Chris Merrill
Concrete Beam Design: Pouring The Foundation To Engineering In T&E Classrooms, Andrew J. Hughes, Chris Merrill
Educational Leadership & Technology Faculty Publications
Ask a middle or high school student if they could design a concrete beam that weighs only 20 pounds and is 36” long but must hold 600 pounds without failing. What is the student likely to say? What if the student was told that, with some optimized decision making based on relatively straightforward mathematics, their beam could hold 2400 pounds or more? The focus of this article is not on concrete beam design, it is rather an introduction to engineering principles in beam design using a lab activity. The concepts and skills learned in this article will lead students into …
Analyzing Concrete Beam Design: Verifying Predictions In T&Ee Classrooms, Andrew J. Hughes, Chris Merrill
Analyzing Concrete Beam Design: Verifying Predictions In T&Ee Classrooms, Andrew J. Hughes, Chris Merrill
Educational Leadership & Technology Faculty Publications
Design is often accepted as a fundamental aspect of engineering (Dym, et al., 2005). The design process is frequently portrayed as a set of steps. However, the design process is more complex than just a set of steps in a relatively fixed process. The complex nature of design, design thinking, questioning, and decision-making is exactly what technology and engineering classrooms are well suited to address. When addressing the question—“Why is technology and engineering education (T&EE) so important?”—the authors believe T&EE’s importance relates to our discipline’s ability to solve complex problems by balancing theory and practice in engaging hands-on learning scenarios …
