Other advantages include increasedretention of knowledge, development of integrated knowledge, and increased motivation1. Thecentral features of PBL include the following: (1) learning is student-centered; (2) studentsidentify, find, and use appropriate resources; (3) students learn group co-operation in all stages ofwork; (4) instructors are facilitators; (5) inter-disciplinary learning where solution of the problemcan extend beyond traditional subject-related boundaries and methods; (6) opportunity to acquiredeeper learning; (7) problems form the stimulus for learning; (8) problems are based on complex,real-world situations; and (9) problems are contextualized to
resinmatrix. It is frequently used in place of a traditional hand layup for a number of reasons,including increased control over resin content, decreased scrap and mess, and generallyimproved reproducibility during processing. [1] Following impregnation of the pre-polymericresin system into fibers, the prepreg is considered B-staged. At this point in processing, the resinhas undergone a partial cure and begun to crosslink. As such, storage in freezers is required, toprevent further crosslinking of the material into a fully cured C-stage product. [2]Prepreg is manufactured primarily using two processes: solvent coating and hot melt coating. Inthe solvent coating process, fabric is threaded between metal rollers and run through a resin bath,then fed

This hindsight led to the development of a questionnaire that could be used in thefuture.1.IntroductionWhetton [1] rightly states that most important professing of a professor, involves histhoughtful choice of reading materials, assignments, activities and most of all learningobjectives. This is even more pronounced when the instructor has to choose few experimentsand a project from a wide variety of mechanical engineering applications. The choice has tobe further developed to meet the learning outcomes called the student outcomes defined byABET [2]. Outcomes are descriptions of the end product of
design emphasis of the class. Anexample of the latter was offered by the U.S. Coast Guard Academy. They incorporate amanufacturing lab component to their sophomore design class, through the construction of a small“air engine.”1 This mixed design/manufacture model was initially considered a good model forNAU and the sophomore D4P design course. However, separation between the design classroomand manufacturing facility locations at NAU eventually dictated that merging the two contexts into asingle offering would be logistically difficult.The Learning Factory concept is an example of comprehensive implementation.2 Developed jointlyby Pennsylvania State University, the University of Washington, and the University of Puerto Rico-Mayaguez, the

A small team of two students worked on the design anddevelopment a robotic work-cell that performs a simple sorting operation for quality control,by utilizing multiple pieces of peripheral equipment. The work-cell was intended to be usedas a part of the curriculum for future sections of the ENGR 4700 as a vision systemslaboratory and an introduction to work-cell design. Further use in ENGR 4950 was alsoplanned to incorporate additional features.The overall goal of the project was to create a small work-cell, as illustrated in Figure 1,including a bowl feeder part loading system, a Fanuc M10iA robot, and a Sony XC-56camera to complete a simple part sorting task. The robot picks up a screw from the feeder,presents it to the

The motivations for us to work on the project are (1) 3D printing technology asnext industrial revolution has caught wide attention around the world. With the development ofthe technology, a custom part that would previously take a great deal of time and money for aprofessional manufacturer to produce can now be made much quicker at a very low cost.Particular for college engineering education, students can produce different innovative parts fortheir new designs for robots or unmanned aerial vehicles using a self-made

However, other forces atplay on a spinning object also register on an accelerometer. The two most significant forces thatact on a spinning object are the centripetal force and gravitational force.

One Week – Bucknell Fabrication Workshop (B-Fab)IntroductionWithin the past decade or more, the increased technological capacity of incoming students –accompanied by a diminished skill-set with regard to traditional hands-on, “tinkering” skills hasbeen discussed in both STEM education as well as mainstream media [1, 2]. Many studentschoose engineering because they want to learn how to design and build the solutions oftomorrow, yet they often do not have dedicated opportunities to expand their hands-on skill setwithin the engineering curriculum. Sadly, traditional curricular instruction in engineering is suchthat students spend the bulk of their first three years learning theory, and relatively little timecontextualizing

Renewable energy, which is estimated tohave provided around 19% of global energy consumption in 2012, has created a globalinvestment trend by drawing in around 249.4 billion USD in 2013 1. With a rapid growth inUnited States clean energy economy, it is deemed vital for emerging young workforce to beknowledgeable and well trained in the field of green energy & sustainable manufacturing. Toaddress this, United States department of labor (DOL) has provided approximately 2 billion USDin funding to community colleges to train emerging workforce in energy and manufacturing 2.
