Course Objectives: The purpose of the course is to provide students with the means of analyzing and designing various machine and load bearing structures. Upon completion of this course, students are expected to obtain:

1. A basic understanding of engineering mechanics and the ability to apply this understanding to analyze and solve a given problem.

2. A basic understanding of material properties and mechanical deformation.

3. The ability to apply advanced science and engineering principles in the design and analysis of structures to support loads within a given limit of safety.

Weekly course schedule

Below is a tentative weekly course schedule. At times, the instructor may slow down to explain a difficult point that students did not understand; at other times, the instructor may speed up the lectures. As the course progresses, the instructor may add new topics (if time permits), or remove certain topics to have more time to go go deeper into other topics or to help student solve more problems in class.

ABET: Contribution of course to meeting the professional component:

EGM 3520 supports several program outcomes enumerated in the Mission Statement of the Department of Mechanical and Aerospace Engineering (MAE). Specific MAE program outcomes supported by this course include: Being able to work professionally in mechanical systems areas including the design and realization of such systems. (ME Program Outcome M4).

Mathematics (25%), Engineering Sciences (50%), Engineering Design (25%)

ABET: Relationship of course to program outcomes:

This course achieves the following Accreditation Board for Engineering and Technology (ABET) outcomes [note that the outcome number corresponds to the respective ABET outcomes (a) through (k)]:

• (a) Apply knowledge of mathematics, science, and engineering [high coverage; method of assessment is through 7 major formal team reports, team presentations, and two exams to measure Outcome (a)]
• (c) Design a system, component or process to meet desired needs [low coverage; method of assessment is through 7 major formal team reports, team presentations, and two exams related to design of trusses, frames and machines for desired functionalities]
• (e) Identify, formulate, and solve engineering problems [high coverage; method of assessment is through 7 major formal team reports, team presentations, and two exams to measure Outcome (e)]
• (f) Understand professional and ethical responsibilities [medium coverage; method of assessment is class examples and through 7 major formal team reports, team presentations of practical applications and designs involving professional engineering ethical application of proper engineering principles learned in statics]
• (g) Communicate effectively [high coverage; method of assessment is method of assessment is through 7 major formal team written reports, team oral presentations to measure Outcome (g)]
• (k) Use the techniques, skills and modern engineering tools necessary for engineering practice [low coverage, no formal assessment to measure Outcome (k)].
