ThisSolutions Manual contains the mathematical steps for solving calculation problems in the chapter exercises of Physics: Modeling Nature. It is a useful supplement for students in homeschooling environments or in traditional classrooms.
This book is considered a student resource and only contains solutions for chapter exercises in the textbook (students already have the answers in the text). This manual is useable for all editions of the textbook.

ENGR211, Statics, is the first course in true engineering that students take at OIT. While the background of the students is varied, a number of them will not have had a first course in linear algebra or vector calculus. Thus, background in the use of vectors to represent forces is provided along with additional background in vector manipulation. Two and three dimensional equilibrium is covered with emphasis on two dimensions. Considerable practice with traditional statics problems is a requirement of the course. Students are taught how to develop equivalent force systems, evaluate equilibrium at points and on rigid bodies, and determine internal forces in trusses, beams, and frames as well as torsion members. Concepts of centroid, moment of inertia, and friction are also developed for further exploration in other courses.
ENGR212, Dynamics, extends the equilibrium concepts in statics to include inertial forces and motion. Kinematics and kinetics of both particles and rigid bodies are developed theoretically and applied to real-world physical problems. Concepts of energy and momentum are included and students are exposed to the multiple ways a single dynamics problem might be solved such that the general concepts presented can be applied to a wide range of specific problems that the student might encounter in the future.
CIV344, Structural Steel Design, is a first course in the design of steel structures according to the AISC Steel Construction Manual and using the recently updated Salmon, Johnson, and Malhas textbook. I address the design of steel members of various standard cross-sections to carry tension, compression, bending, torsion, and combined loads. Vertical loading in buildings according to ASCE 7 is covered and used to develop load cases for design problems. Whole building design examples are used to place structural members in context and the 3D structural analysis program RISA is used to perform analysis and design and is checked by hand. The class also treats the design of bolted and welded tension and eccentric connections. Exams are generally take-home and consist of complete member design with checking of all appropriate limit states.
CIV358, Project Management, addresses a range of material, but focuses primarily on contracting, estimating, scheduling, and green building methods. Various formats for the class have been attempted so far, but at this point the class uses a textbook to provide exposure to contracting concepts, in-class work to reinforce the reading and develop hard skills in estimating (RS Means catalogs) and scheduling (CPM via Microsoft Project). Green building concepts are addressed via readings, examination of LEED reference guides, and in-class discussion and presentations. This year, a group term project combines these various topics in the form of pre-construction services for a Habitat for Humanity home. The students have been provided with information on existing lots owned by the local HFH branch and they are developing a construction schedule, estimate, and plans for a home of their own design. The home will incorporate energy-efficiency measures and high-performance building concepts, which will be reinforced by a visiting lecture from Clark Brockman of SERA Architects in Portland.
CIV407, Bridge Design, exposes the students to the AASHTO LRFD Bridge Design Specifications. Steel girder and concrete deck designs are incorporated into the class and a final project requires a generalized (and often incomplete) design of a whole bridge. Future offerings of the class may require that the design be single-span while treatment of multi-span scenarios will be covered in lecture. A tour of area bridges is included and students are required to provide feedback on bridges of different eras and the changing technology and structural forms implemented in each. A Masters-level bridge rating class is also planned that would follow the design course to introduce students to overload routing and rating of bridges for inventorying.
Statics is the fundamental basis for continued study in solid and fluid mechanics, machine design, and structural analysis. Upon completion of the course you will have an intimate understanding of the concept of static equilibrium and its application to rigid structural and mechanical systems. Specifically, you will be able to analyze the internal and reaction forces of loaded systems made up of axial, torsional, and beam type members.
3. You work all homework problems on your own and check with the solutions in the manual using the available solutions appropriately. You build your confidence with the material. This is a good thing, but you can also do this without the solutions manual!
Website: Blackboard CE will be used to post homework assignments and solutions, exam solutions, and general announcements. I will email your OIT address occasionally with updates, clarifications, or comments.
Dynamics is the study of particles and rigid bodies in various types of motion (rotary, linear, curvilinear). The application of these concepts is broad and appropriate for both mechanical engineering students concerned with moving parts within machines and civil engineering students concerned with the dynamics of fluids or structures. This course will be restricted to planar motion although the extension to three dimensions is quite easy. Vibrations may be considered if time permits.
o Do units agree with the type of result obtained? Does the value make sense based on your real-world experience? Is there a second way of solving the problem that would allow you to confirm your answer?
