OBJECTIVES:

Learn to perform stress and deformation analysis of simple structures subjected to tension, compression, torsion, or bending. Learn to analyze failure under combined loading. Develop the knowledge base required for applications and design.

 

PREREQUISITES:

EM 306 or 306S with a grade of at least C, and M 408D or 308L with a grade of at least C.

 

KNOWLEDGE, SKILLS, AND ABILITIES STUDENTS SHOULD HAVE BEFORE ENTERING THIS COURSE:

The student must have a firm grasp of algebra, geometry, trigonometry, and calculus. Knowledge of differential equations is helpful, but not necessary. Concepts of mechanics covered in typical physics courses are also essential. The student should have a good command of the material covered in EM 306 Statics - ideas of equilibrium, free-body-diagrams, properties of sections such as centroids and second moments are essential for this course.

 

KNOWLEDGE, SKILLS, AND ABILITIES STUDENTS GAIN FROM THIS COURSE:

Fundamental concepts of solid mechanics, including stress, strain, and displacement; analysis and design of simple structure members subjected to tension, compression, torsion, and bending; elementary models of material deformation and failure behavior.

 

IMPACT ON SUBSEQUENT COURSES IN CURRICULUM:

Mechanics of solids is a basic engineering subject concerned with the strength and performance of solids and structures and therefore essential in many engineering applications. The course is an essential prerequisite for the more advanced mechanics courses, such as EM339, ASE 221K, 324L, CE 329, and ME 336, 338, and each of these courses is prerequisite for more advanced design courses in aerospace engineering, civil engineering, and mechanical engineering.

INTEGRITY POLICY:

ALL work that you turn in for grading MUST be your own work, not work that is copied from some other source. University policies and procedures will be followed strictly whenever academic dishonesty is suspected.

 

HOMEWORK POLICY:

Late homework will not be accepted.

Show a complete solution, with all the intermediate steps and calculations, to receive full credit for homework.

Turn in your homework on a standard 8.5 x 11 paper, stapled together. Write clearly.

Graded homework problems will be returned to you one week later during Tutorial sessions.

Solutions to the homework problems will be discussed in the recitation/tutorial sections.

You may study together, but your solutions should be your own.
