Explore what makes a reaction happen by colliding atoms and molecules. Design experiments with different reactions, concentrations, and temperatures. When are reactions reversible? What affects the rate of a reaction?

The concepts of stability and equilibrium are introduced while students learn how these ideas are related to the concept of center of mass. They gain further understanding when they see, first-hand, how equilibrium is closely related to an object's center of mass. In an associated literacy activity, students learn about motion capture technology, the importance of center of gravity in animation and how use the concept of center of gravity in writing an action scene.
Students learn that engineers develop different polymers to serve various functions and are introduced to selectively permeable membranes. In a warm-up activity, they construct models of selectively permeable membranes using common household materials, and are reminded about simple diffusion and passive transport. In the main activity, student pairs test and compare the selective permeability of everyday polymer materials engineered for food storage (including plastic grocery bags, zipper sandwich bags, and plastic wrap) with various in-solution molecules (iodine, corn starch, food coloring, marker dye), assess how the polymer’s permeability relates to its function/purpose, and compare that to the permeability of dialysis tubing (which simulates a cell membrane).
General principles of separation by equilibrium and rate processes. Staged cascades. Applications to distillation, absorption, adsorption, and membrane processes. Phase equilibria and role of diffusion. 10.32 will be offered for 6 units starting spring 2004.
Statica is de leer van mechanisch evenwicht.
Een lichaam beweegt niet (of is in een éénparige rechtlijnige beweging) als de som van de krachten die op dat lichaam werken nul is. Als ook de som van de momenten die op dat lichaam werken nul is, dan roteert het lichaam ook niet.
De consequentie van deze twee evenwichtsvoorwaarden (som van krachten =0 en som van momenten =0), is dat voor een lichaam waarop een aantal bekende krachten werken de (onbekende) reactiekrachten bepaald kunnen worden .
Dit is van groot belang omdat de grootte van de reactiekrachten de dimensionering en materiaalkeuze van toe te passen componenten bepalen.
Binnen het vak “Statica” wordt in detail ingegaan op de verschillende mechanische belastingen, vaak voorkomende constructies en hoe te rekenen met de diverse belastingen.
Statics deals with the principles of equilibrium. In this course the principles of forces and moments will be explained as well as principle of equilibrium of forces and moments. This also includes the equilibrium of 2D and 3D structures and trusses. Furthermore the principle of internal forces and moments is addressed as well as the use of the principle of virtual work to calculate both external and internal loads. Finally, the concepts of centre of gravity, centroids and moments of inertia are discussed
Students are introduced to static equilibrium by learning how forces and torques are balanced in a well-designed engineering structure. A tower crane is presented as a simplified two-dimensional case. Using Popsicle sticks and hot glue, student teams design, build and test a simple tower crane model according to these principles, ending with a team competition.
This subject deals primarily with equilibrium properties of macroscopic systems, basic thermodynamics, chemical equilibrium of reactions in gas and solution phase, and rates of chemical reactions.
To learn about the concept of center of mass, students examine how objects balance. They make symmetrical cut-outs of different "creatures" and experiment with how they balance on a tightrope of string. Students see the concept of center of mass at work as the creatures balance.
What is economics and why should you spend your time learning it? After all, there are other disciplines you could be studying, and other ways you could be spending your time. As the Bring it Home feature just mentioned, making choices is at the heart of what economists study, and your decision to take this course is as much an economic decision as anything else.
Economics is probably not what you think it is. It is not primarily about money or finance. It is not primarily about business. It is not mathematics. What is it then? It is both a subject area and a way of viewing the world.
Students are introduced to the concept of viscoelasticity and some of the material behaviors of viscoelastic materials, including strain rate dependence, stress relaxation, creep, hysteresis and preconditioning. Viscoelastic material behavior is compared to elastic solids and viscous fluids. Students learn about materials that have viscoelastic behavior along with the importance of engineers understanding viscoelasticity. To best engage the students, conduct the first half of the associated Creepy Silly Putty activity before conducting this lesson.
Students learn how common pop culture references (Harry Potter books) can relate to chemistry. While making and demonstrating their own low-intensity sparklers (muggle-versions of magic wands), students learn and come to appreciate the chemistry involved (reaction rates, Gibb's free energy, process chemistry and metallurgy). The fun part is that all wands are personalized and depend on how well students conduct the lab. Students end the activity with a class duel a face-off between wands of two different chemical compositions. This lab serves as a fun, engaging review for stoichiometry, thermodynamics, redox and kinetics, as well as advanced placement course review.
