EM 214 - Statics – Fall 2004
S. Bang, Professor Credits: (3-0) 3 credits
South Dakota School of Mines & Technology CB 206W 8-8:50 am
MWF
Section 01
Course Description: Prerequisite
Math 125 completed with a grade of “C” or better. The study of
external
forces acting on stationary rigid bodies in equilibrium. Vector algebra
is
used to study two and three-dimensional systems of forces. Trusses, frames and
machines,
shear and moment in beams. Friction,
centroids, moments of inertia and
mass
moments of inertia are discussed.
Course Objective: This
course is designed to provide students with a basic knowledge for the analysis
of
the
effects of external forces acting on stationary rigid bodies in equilibrium.
Course Outcomes: The
students successfully completing this course will have the ability to:
1.
Determine the components
of a force in rectangular coordinates
2.
Draw complete and
correct free-body diagrams and write the appropriate
equilibrium
equations from the free-body diagram.
3.
Evaluate forces acting
on static bodies including determining resultants
and
3D components
4.
Calculate moments in 2D
and 3D about a point and an axis utilizing
cross
products and dot products.
5.
Determine the support
reactions on a structure.
6.
Determine the connection
forces in trusses and in general frame structures.
7.
Given standard shapes
and corresponding centroids and or moment of inertia
be
able to compute centroids and or moment of inertia for composite bodies.
8.
Determine how to
identify and solve problems involving dry friction, wedges
and
belt friction.
9.
Determine the internal
reactions in a beam, draw correct shear force and
bending
moment diagrams.
Text: Engineering Mechanics STATICS, 10TH Ed., R.C.
Hibbeler. You are
required
to bring your text to every class. Your
book is your portable
instructor. It is available 24/7. I suggest you use it – read the text and
study the
examples.
Supplies: Engineering paper
for all homework, engineering pencil, straight edge, scientific calculator.
Homework: Homework will be due
at the beginning of the next class period.
Staple all pages together.
Homework must be prepared in a professional manner. Use a straight edge
for figures and free body diagrams. Homework more than one week late will
not be accepted. No homework accepted after the last day of class.
Late homework is 20% off/calendar day.
Academic integrity:
Cheating of any type will result in an F in the course; this includes
the copying of
homework.
Attendance: Students with five absences will
be asked to withdraw from the class.
Grading: 90-100 A
Tests 60% 80
– 89 B
Final 20% 70
– 79 C
Homework 20% 60 – 69 D
Tests: Tests will be given outside of
the normal class time, during the
common
exam time, as indicated. No low scores
will be dropped. No makeup and no
retakes on tests. You are allowed one 8.5 x 11 inch crib sheet.
Office: Civil Mechanical Building Rm:
237, MWF 1-2 PM or by appointments.
Phone: 394-2440. Ms. Lois Arneson-Meyer, instructor of
Section 02, will be available
for study table in the Library or Miners Shack during
designated times.
FBD’s: Free Body Diagrams must be shown
on all answers to homework and exam
questions
as appropriate. FBD’s must include
forces, distances, dimensions,
angles,
and directions as appropriate in addition to any other parameters
necessary
to understand and/or solve the problem.
Answers without FBD’s
will
not be graded and will count as zero.
Final Exam: All students are required to take the final exam at the assigned period during final exam week.
Students with special needs
or requiring special accommodations should contact the instructor, Sangchul
Bang at 394-2440 (lois.arneson-meyer@sdsmt.edu) and/or the campus ADA
coordinator, Jolie McCoy, at 394-1924 at the earliest opportunity.
