Course objectives and outcomes

Catalog description: Stress and strain at a point, stress-strain-temperature relations and mechanical properties of materials. Systems subject to axial load, torsion and bending. Design concepts, indeterminate structures, applications.

The objective of this course is to teach how to analyze stress and strain in structural components subject to axial, torsional and bending loads. The course exposes students to analytical methods for computing stresses and strains in static structures.

Course assessment

Homework assigned every week must be submitted at the beginning of class on the due date. Solutions will be posted promptly so late homework will not be accepted.

Examinations: There will be four in-class examinations in addition to the final exam. The exam dates are listed in the syllabus.

Grading: In class exams: 60%, Final exam: 20%, Homework: 20%

Other course information

Attendance is very important and you are responsible for knowledge of all scheduling and policy announcements in class.

Academic Honesty: All students admitted to the University of Florida have signed a statement of academic honesty committing themselves to be honest in all academic work and understanding that failure to comply with this commitment will result in disciplinary action. This statement is a reminder to uphold your obligation as a student at the University of Florida and to be honest in all work submitted and exams taken in this class and all others.

Students with disabilities who are requesting classroom accommodation must first register with the Dean of Students Office.  The Dean of Students Office will provide documentation to the student who must then provide this documentation to the Instructor when requesting accommodations.
