Grading: Three Midterm Exams 20% each, Final Exam 30%, Homework 10%
Final course grade is determined using a normal distribution curve. Grade distribution:
Grade A
average plus one standard deviation and higher
Grade B
average plus ½ standard deviation
Grade C+
average
Grade Caverage minus ½ standard deviation
Grade F
average minus one standard deviation and lower
Homework - homework assignments are due on Wednesday and of the week shown in course schedule. No
late homework will be accepted. Homework problems will be reviewed in the class and the solutions will be
posted on the Mechanical and Aerospace Engineering website (www.engr.sjsu.edu/mae) under part time
faculty web pages.

Course Goals
1. To learn the fundamental of static equilibrium as applied to structures.
2. To develop the ability to analyze a problem in a simple and logical manner and to apply to its solution
the basic principles.
Student Learning Objectives
Students should demonstrate the ability to:
1. Draw a free-body diagram showing all forces acting on the body.
2. Apply the equations of equilibrium to solve for unknown reactions in a structure.
3. Determine the centroids and centers of gravity of lines, areas and volumes.
4. Determine the internal forces in trusses, frames, machines and beams.
5. Draw a shear and moment diagram for a structure under load and to determine the
maximum values of shear and moment.
6. Calculate the area and mass moment of inertia.
7. Analyze structures acted on by friction forces.
