Students conduct several simple lab activities to learn about the five fundamental load types that can act on structures: tension, compression, shear, bending, and torsion. To learn the telltale marks of failure caused by these load types, they break foam insulation blocks by applying these five load types, carefully examine each type of fracture pattern (break in the material) and make drawings of the fracture patterns.

Students build model caverns and bury them in a tray of sand. They test the models by dropping balls onto them to simulate an asteroid hitting the Earth. By molding papier-mache or clay around balloons (to form domes), or around small cardboard boxes (to form rectangular structures), students create unique models of their cavern designs.

Students gain experience using the software/systems (engineering) design process, specifically focusing on the testing phase. This problem-based learning activity uses the design process to solve open-ended challenges. In addition to learning about test cases for testing software, students utilize the design process as a vehicle to work through a problem and arrive at a solution.

JUnit is a testing method that is included with NetBeans (Java) installs or can be downloaded from the web and included in the Java build. In this activity, students design tests for a provided Java class before the class methods are constructed using a process called test-driven development. To create a design, the software/system design process, which is a specific case of the engineering design process, is followed. After students create a design, it is implemented and tested and if necessary, the design undergoes editing to make sure it functions by testing the Java class correctly. To conclude the activity, students write the methods in the Java class using their tests to debug the program.

With the challenge to program computers to mimic the human reaction after touching a hot object, students program LEGO® robots to "react" and move back quickly once their touch sensors bump into something. By relating human senses to electronic sensors used in robots, students see the similarities between the human brain and its engineering counterpart, the computer, and come to better understand the functioning of sensors in both applications. They apply an understanding of the human "stimulus-sensor-coordinator-effector-response" framework to logically understand human and robot actions.
Doelstelling van dit college is een introductie te geven in de theorie …
Doelstelling van dit college is een introductie te geven in de theorie van de Thermodynamica, een van de fundamentele werktuigbouwkunde vakken. De Thermodynamica behandelt energie vraagstukken en relaties tussen de eigenschappen van materialen. In dit college wordt voor een ingenieurs aanpak van de Thermodynamica gekozen: onderwerp van studie zijn systemen en hun interactie met de omgeving. Naast gesloten systemen krijgen open systemen veel aandacht. Thermodynamica wordt, in combinatie met stromingsleer en warmte- en stofoverdracht, ingezet om bijvoorbeeld automotoren, turbines, compressoren, pompen, elektriciteit opwekkinginstallaties, cryogenische-, koel- en klimaat-installaties en duurzame energieconversie installaties te analyseren en ontwerpen. De beginselen van de Thermodynamica maken het mogelijk om de ontwerpen van energie gerelateerde werktuigbouwkundige apparaten en systemen te optimaliseren voor het betreffende doel.
De thermodynamische relaties voor compressibele stoffen en de fasendiagrammen voor pure stoffen …
De thermodynamische relaties voor compressibele stoffen en de fasendiagrammen voor pure stoffen worden behandeld. Enkele voorbeelden van toestandsvergelijkingen worden behandeld (de viriaal vergelijking, vergelijkingen met twee constanten en vergelijkingen met meerdere constanten). De grootheden Helmholtz energie en Gibbs energie worden geintroduceerd. De Gibbs vergelijking is de basis om tot een beschrijving van evenwichten (van mengsels) te komen. De condities van evenwicht van pure componenten en van mengsels wordt afgeleidt. Uitgaande van de totale differentialen worden partiele afgeleide uit gedrukt in termen van thermodynamische grootheiden. Voor de berekening van processen, zo als compressie, expansie enz worden uitdrukkingen afgeleid voor delta h, delta s en delta u (waarbij delta voor de deviatie="departure" van ideaal gas gedrag staat). Het wordt getoond hoe deze uitdrukkingen (of dimensieloze diagrammen van deze grootheden) voor de berekening van processen gebruikt kunnen worden. Ook wordt de grootheid exergie gepresenteerd, een grootheid die gebaseerd is op de tweede hoofdwet van de thermodynamica, tezamen met enkele nuttige grootheden en hulpmiddelen voor het uitvoeren van exergie analyses (exergie verlies, exergie rendementen, waardediagram). In dit college wordt de definitie van exergie beperkt tot de thermo-mechanische exergie. Het principe van het stoomturbine kringproces wordt getoond en mogelijkheden voor de optimalisatie van dit kringproces worden besproken, zoals de keuze van stoomdruk en -temperatuur en de toepassing van stoomoververhitting en -herverhitting.

This lesson is an introductory topic in thermodynamics, on the conversion of energy. The aim of this video is to support students in visualizing the conversion of energy and its importance in real world applications. For this reason, everyday examples are used to help students see the conversion of energy around them. Energy conversion is explored through a simple example of generating electricity for lighting up a shadow puppetry play in a village. The chain process of energy conversion is illustrated until the end product of electricity. This example of electricity generation is further illustrated in an actual industrial setting by taking the viewers to a Power Plant, where viewers will see and hear the explanation of a mechanical engineer on the equipment used to produce electricity that we use in homes and businesses. This important concept of energy conversion is crucial for students to understand as a basis for learning other concepts in Thermodynamics.

Prior to reaching households, water is exposed to a variety of treatments designed to render it fit for human consumption and use. One of the first treatment steps is the removal of suspended solids using chemical additives called flocculants. In this activity, students learn about two commonly used flocculants and clean water collected from a local pond or river. They experiment with flocculant, stirring and pH variables.

Students show their creativity and think like engineers as they design products or services that can be used to improve environmental problems in the community. While being aware of the steps of the engineering design process, students are challenged to consider all aspects of their products/services, including their costs, and impacts on the environment and people in their communities. They present their "green" solutions, in the form of advertisements, to the class for critical review of their feasibility.
