Engineering Mechanics 311  -   Mechanics of Materials
Summer Quarter 1997 / 9:45-11:00 MWF / BH 326


 
PRIMARY GOAL: To acquaint students with the mechanics of deformable bodies, including analysis of stresses, strains, and deflections in bodies subjected to axial, torsional, and bending loads.

GRADING:

                Homework and Pop Quizzes                10%
                Computer Project                        10%
                Exam 1                                  20%
                Exam 2                                  20%
                Exam 3                                  20%
                Comprehensive Exam                      20%


GRADING SCALE:

        A       90 - 100%       (highest degree of excellence)
        B       80 - 89%        (superior)
        C       70 - 79%        (average)
        D       60 - 69%        (minimum quality of work to receive course credit)
        F       < 60%           (failure)
Note: The lower limit in each grade range may be lowered slightly such that the division between letter grades occur at any large gaps in the grade spectrum. This adjustment will be determined only after the final averages are computed and may or may not alter the grade scale.
