Jablokow Office Randell 115 Email Office Hours Teaching Assistants Alka Basnet Jasen Carroll By appointment, via email By appt, via email By appt, via email Designation: Required Catalog Description: Covers intermediate static mechanics, an extension of the fundamental concepts and methods of static mechanics introduced in the freshman courses TDEC 111, TDEC 113, and TDEC 115. Includes topics such as problem formulation and solution methods; two‐and three‐dimensional vector representation of forces, moments and couples; static equilibrium of particles, rigid bodies, and engineering structures; analysis of external and internal forces in structures via methods of free body diagrams; and properties of cross‐sectional areas. Prerequisites: TDEC 113 ‐ Physics Fundamentals of Engineering II (Minimum Grade: D) or Physics 185 – Physics I (Minimum Grade: D) or Physics 111 – Physics I (Minimum Grade: D) Textbook and On‐line Resources: Engineering Mechanics – STATICS with Mastering Engineering Package, 12th Edition, R.C.

The website for Mastering Engineering is Course ID: MEM202201115 Course Objectives: This course provides the starting engineering students with a smooth transition from science‐based mechanics problems to engineering‐based mechanics problems, i.e. from equilibrium of relatively simple force systems to force systems in structures with connected members and with complex geometry. The specific objectives are: 1. Develop equilibrium equations for particles 2. Draw free body diagrams 3. Determine the resultants of a force and couple system 4. Reduce a force and couple system 5. Reduce a distributed load into a resultant force 6. Develop equilibrium equations for rigid bodies 7. Apply the method of joints and method of sections to solving truss problems 8. Develop equilibrium equations for frames and machines 9. Determine internal forces in structural members 10.

Attendance of less than 80% will result in an F grade for the course. On‐Line Assignments: Access is required to: If you purchase the book at the Drexel bookstore, the access is included in the price of the book. Otherwise, you can purchase access at the website. It will not be possible to complete the on‐line assignments late, but they will be available for review to study for exams. There aremany tutorial assignments included on‐line. These assignments will be graded by the system. Course ID: MEM202201115 Homework Assignments (HW): For each lecture there will be an on‐line homework assignment consisting of tutorial, fundamental, and end‐of‐section problems from the book for the current week’s content. The due date is the next lecture. Homework is graded by the system. Tutorials are extra credit, fundamental problems are practice, and end‐of‐section problems are for credit and should take about an hour to complete. Quiz (QZ): On Friday there will be an on‐line quiz held on Mastering Engineering consisting of one (1) problem on the current week’s material. You will have 30 minutes to complete the quiz. Mid‐term Examination (ME): There will be two (2) one‐hour mid‐term examinations held during lecture in the 5th and 9th week of the term. The mid‐terms will consist of four (4) problems and will be paper based. Final Examination (FE): Final examination will be held as scheduled by the University. The Final Exam will be cumulative, covering the material taught in the entire term, with primary focus on the material covered after the mid‐term examination. The final exam will consist of six (6) problems and will be paper based. Grading: HW – 15%; QZ – 10%; ME1 – 25%; ME2 – 25%; FE – 25% There will be no curved grades.
