Objectives

This course is an introduction to the field of solid mechanics. The course deals with the study of 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. 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.

Prerequisites

Statics.

Attendance Policy

In keeping with published policy (see p. 28 of the 1995-96 Rowan Undergraduate Catalog), attendance is required because substantial in-class material is presented. Points will be deducted from the final grade for unexcused absences. The instructor must be notified of an excused absence in advance of the class. Sleeping in class is forbidden. Notebooks, textbooks and calculators should be brought to each class. A group report will be required for each laboratory. It is imperative that all group members participate in writing as well as interpreting the data. Students not participating in their group’s work will have a percentage of the grade deducted, based on feedback from the other group members.

Performance Expectations

You are encouraged to work on homework assignments and exchange ideas with your classmates, but the assignment and calculations should reflect your individual effort. Points will be deducted for unprofessional presentation, unstapled sheets and missing names.

This course is only offered for grade credit. The grade is determined by evaluating work performed in the listed areas:

Attendance & Professionalism 5%
Homework 5%
Classwork & Quizzes 30%
Midterm 25%
Final Exam 35%

All work must be submitted at the beginning of the class period on the due date. Accommodation may be granted for special circumstances but must be supported by proper documentation. If a student is excused, he/she will be given a reasonable opportunity to make up such work. Late work will be penalized 20% of the maximum possible score for each calendar day delay. An assignment submitted more than four days late will be given a zero score. Units on the final answer. No units, no credit.

Unannounced quizzes will be given as required on material we have already covered.

Any form of cheating, plagiarism, and/or academic dishonesty will result in an "F" grade in the course for the individual(s) involved.

A 1-hour closed book midterm examination will be given approximately the 8th week of class. A one-page 8-1/2 x 11 inch formula sheet (prepared by the student) is permitted.

A 2-hour final exam will be given during the final exam week. The final exam is not comprehensive, except for concepts and core material. A one-page 8-1/2 x 11 inch formula sheet (prepared by the student) is permitted.

Partial credit will be given to incorrectly solved problems, as long as the solution reflects basic understanding of the material.

Special Accommodations

Your academic success is important. If you have a documented disability that may have an impact upon your work in this class, please contact me. Students must provide documentation of their disability to the Academic Success Center in order to receive official University services and accommodations. The Academic Success Center can be reached at 856-256-4234. The Center is located on the 3rd floor of Savitz Hall. The staff is available to answer questions regarding accommodations or assist you in your pursuit of accommodations. We look forward to working with you to meet your learning goals.
