This eBook was written as the sequel to the eBook titled DC Circuits, which was written in 2016 by Chad Davis.
This eBook covers Alternating Current (AC) circuit theory as well us a brief introduction of electronics. It is
broken up into seven modules. Module 1 covers the basic theory of AC signals. Since only DC sources are used in
the first eBook, details of AC signals such as sinusoidal waveforms (or sine waves), square waves, and triangle
waves are provided. Module 2, titled AC Circuits Math Background, covers the mathematics background needed
for solving AC circuit problems. The background material in Modules 1 and 2 are combined in Module 3 to solve
circuits with AC sources that include resistors, inductors, and capacitors (RLC circuits).

In this professional development session, we will develop a shared understanding of how formative assessment works and different approaches that have been developed. The material for this resource come from a series of PD sessions on formative assessment developed by the ACESSE team: Philip Bell, Shelley Stromholt, Bill Penuel, Katie Van Horne, Tiffany Neill, and Sam Shaw.We will be updating this Facilitator's Guide for ACESSE Resource A with the most up-to-date information about this resource over time.

Abstract: This session provides a step-by-step process to support participants as they design a 3D assessment task for the science classroom. Along the way, they learn how to define 3D learning performances for specific lessons—and how to use a range of tools to support their assessment design work. A key goal of the session activity is to improve the connection of intended learning goals to assessment practices. Participants build their 3D assessment design capacity by designing and workshopping tasks—before piloting them in their classrooms. The approaches learned in this workshop can be used with any curricula, at any grade level, and across all subjects of science. 

Overview: In this workshop, we will build our capacity to identify the range of intellectual resources students use as they make sense of phenomena. We will first explore how equity and justice relate to culture-based approaches to pedagogy—and then focus on how to identify and leverage the resources students use in moments of sensemaking. This resource can also be used by individuals wanting to learn how equity involves promoting the rightful presence of all students across scales of justice, desettling inequities, and supporting expansive learning pathways. This workshop provides participants with an opportunity to explore important theoretical ideas by exploring examples of how learners engage in diverse sense-making. Participants will learn about some of the challenges that less expansive learning environments can cause for learners from non-dominant communities. This resource is estimated to take between 161-268 minutes (2 ⅔ - 4 ¾ hours), depending on the choices of the facilitator in scenario selection.

An essential and practical text for both students and teachers of AC electrical circuit analysis, this text picks up where the companion DC electric circuit analysis text leaves off. Beginning with basic sinusoidal functions, ten chapters cover topics including series, parallel, and series-parallel RLC circuits. Numerous theorems and analysis techniques are examined including superposition, Thévenin's theorem, nodal and mesh analysis, maximum power transfer and more. Other important topics include AC power, resonance, Bode plots and an introduction to three-phase systems. Each chapter begins with a set of chapter objectives and includes a summary and review questions. A total of over 500 end-of-chapter exercises are included. A companion laboratory manual is available.

This course introduces the basic components of an airframe structure and discusses their use and limitations. The realities of composite design such as the effect of material scatter, environmental knockdowns, and damage knockdowns are discussed and guidelines accounting for these effects and leading to robust designs are presented.

The resulting design constraints and predictive tools are applied to real-life design problems in composite structures. A brief revision of lamination theory and failure criteria leads into the development of analytical solutions for typical failure modes for monolithic skins (layup strength, buckling under combined loads and for a variety of boundary conditions) and stiffeners (strength, column buckling under a variety of loads and boundary conditions, local buckling or crippling for one-edge and no-edge-free conditions). These are then combined into stiffened composite structures where additional failure modes such as skin-stiffener separation are considered. Analogous treatment of sandwich skins examines buckling, wrinkling, crimping, intra-cellular buckling failure modes. Once the basic analysis and design techniques have been presented, typical designs (e.g. flange layup, stiffness, taper requirements) are presented and a series of design guidelines (stiffness mismatch minimization, symmetric and balanced layups, 10% rule, etc.) addressing layup and geometry are discussed. On the metal side, the corresponding design practices and analysis methods are presented for the more important failure modes (buckling, crippling) and comparisons to composite designs are made. A design problem is given in the end as an application of the material in this Part of the course.

This course is designed to introduce students who wish to specialize in stress analysis of thin-walled structures to more advanced topics such as the analysis of statically indeterminate structures, warping, constraint stresses, shear diffusion, and elements of plate bending.

Aerodynamics and Aircraft Performance, 3rd edition is a college undergraduate-level introductory textbook on aircraft aerodynamics and performance. This text is designed for a course in Aircraft Performance that is taught before the students have had any course in fluid mechanics, fluid dynamics, or aerodynamics. The text is meant to provide the essential information from these types of courses that is needed for teaching basic subsonic aircraft performance, and it is assumed that the students will learn the full story of aerodynamics in other, later courses. The text assumes that the students will have had a university level Physics sequence in which they will have been introduced to the most fundamental concepts of statics, dynamics, fluid mechanics, and basic conservation laws that are needed to understand the coverage that follows. It is also assumed that students will have completed first year university level calculus sequence plus a course in multi-variable calculus. Separate courses in engineering statics and dynamics are helpful but not necessary. Any student who takes a course using this text after completing courses in aerodynamics or fluid dynamics should find the chapters of this book covering those subjects an interesting review of the material.

The 236-page text was created specifically for use by undergraduate students in Aerospace Engineering and was based on Professor Marchman’s many years of experience teaching related subject matter as well as his numerous wind tunnel research projects related to aircraft aerodynamics and his personal experience as the owner and pilot of a general aviation airplane. It has been used at Virginia Tech and other universities.

Welcome to this course of Aerospace Mechanics of Materials. We are happy that you chose to join us on this exciting journey. This course deals with basic material and geometry dependent analysis of structures. In this course, you will investigate how these material properties, in combination with structural geometries, affect the design and performance of basic structural elements under axial, torsion, bending and shear loading.

We have divided this course into eight different subjects and a review chapter. In those subject, you will find video lectures and readings, where the concepts and theory will be explained; examples, where we will solve a problem for you, so you can reinforce the concepts you have learned; and exercises, that will allow you to test your knowledge.

Aerospace Structures by Eric Raymond Johnson is a 600+ page text and reference book for junior, senior, and graduate-level aerospace engineering students. The text begins with a discussion of the aerodynamic and inertia loads acting on aircraft in symmetric flight and presents a linear theory for the status and dynamic response of thin-walled straight bars with closed and open cross-sections. Isotropic and fiber-reinforced polymer (FRP) composite materials including temperature effects are modeled with Hooke’s law. Methods of analyses are by differential equations, Castigliano’s theorems, the direct stiffness method, the finite element method, and Lagrange’s equations. There are numerous examples for the response axial bars, beams, coplanar trusses, coplanar frames, and coplanar curved bars. Failure initiation by the von Mises yield criterion, buckling, wing divergence, fracture, and by Puck’s criterion for FRP composites are presented in the examples.
