Solid Mechanics
Fall 2001

 

Catalog Description

This course is an introduction to the field of Solid Mechanics. The course consists of studying the behavior of structural members and machine components under applied loading. The applied loads consist of axial forces, transverse forces, torques, moments and combinations thereof.  These loads, which are transmitted through structural members and machine components via internal stresses, result in deformations of these components (i.e. strain). Structural members and machine components are modeled as bars, shafts, beams and columns, which stretch, twist, bend and buckle under applied loads. Implications of mechanical behavior on the design of machine components and structural members are stressed throughout the course.

Grading

Homework (25%).  Approximately 10 homework problems per week will be assigned.  Assignments must be done on engineering paper in the format specified by the instructor (Known, Find, Given, Diagram, Analysis).  A sample of the required format is attached.  Assignments are due at the beginning of the class on the day announced by the instructor.  Late assignments will not be collected (Late = 0), but the lowest homework grade will be dropped.  Homework will be done in teams as described on page 3.

Weekly Quizzes (20%). A short quiz will be given on each day that the homework is due and will cover the same material as the homework that is being turned in.  The quizzes will be begin promptly at 8 a.m. and will be timed (approx. 10 minutes).  No make up quizzes will be given for any reason (please don’t even ask).  The lowest quiz score will be dropped.

Midterm Exam (25%). A 1-hour midterm examination will be given approximately the 4th week of class. 

Final Exam (30%).   A 2-hour comprehensive final exam will be given during finals week. A one-page 8 1/2 x 11 inch formula sheet (prepared by the student) is permitted. 

Attendance Policy

Attendance at each class is absolutely required.  Sleeping in class is forbidden.  Notebooks and calculators should be brought to each class.

Problem Sessions

In addition to the regular class hours, a "voluntary" problem session will be held one evening each week.
