Course DescriptionRelationships between stress and strain in deformable solids is studied. Analysis is applied to axially-loaded members, circular shafts, beams and columns. Combined stresses, statically indeterminate systems and properties of structural materials are included. Prerequisites: ENGR 211. Audit available.
Intended Outcomes for the course
Upon successful completion of this course, the student will have satisfactorily accomplished the goals and objectives listed in this course content guide. Course content guides are developed by collegewide Subject Area Curriculum Committees and approved by management.
Course Activities and Design
Emphasis is on problem-solving using the three basic tools of mechanics, namely:
a. the equilibrium relationship
b. the geometric compatibility relationship
c. the force-displacement relationship
Principles and techniques are presented through lectures and demonstrations. Students develop problem-solving skills during working sessions under the guidance of instructor. Problems are assigned on a weekly basis for practice. Practical applications are made throughout the course by introducing many typical engineering design problems involving beams, shafts, columns and pressure vessels.
Outcome Assessment Strategies
Student progress is measured by performance on homework and on examinations covering appropriate types of problems. Details will be provided by the instructor at the initial class meeting.
