Prerequisite: ENGR 309 (Introductory Mechanics)

Summary : Continuation of ENGR 309 covering advanced topics (sections asterisked in text) in chapters listed below.

I. Equilibrium of rigid body systems

• distributed forces, centroids of curved surfaces subjected to fluid pressure (Ch. 5).
• 3D (space) trusses (Ch. 6).
• shear and bending moment diagrams for planar frames and machines (Ch. 7).
• planar inextensible cables (Ch. 7).
• friction in machine parts (Ch. 8).
• product of inertia, principle moments, transformation of axes, Mohr's circle (Ch. 9).
• virtual work (Ch. 10).

II. Motion of particles and rigid body systems

• work-energy and impulse-momentum principles applied to particles (Chs. 13,14).
• work-energy and impulse-momentum principles applied to planar rigid body systems (Chs. 16, 17).
• free vibrations of single-degree-of-freedom mechanical systems (Ch. 19).

Grading Summary: Two midterm exams will cover most asterisked topics in Chs. 5-9 and select topics in Chs. 10,13,14, respectively. The final exam will cover all material presented during the course with emphasis on Chs. 16,17,19.

Grader: The instructor
Grading Basis:

Midterm Exams I, II................................................. 40 % ( 20 % each)
Final Exam (Comprehensive)................................. 25 %
Homeworks (Excl. Programming)........................... 25 %

Computers/Programming: A student account on Sunset will be required for email and web access. Software on Sweetgum and the PC's in the Engineering Microcomputer Lab and Weir Hall is recommended for simple programming assignments. Example MATLAB and FORTRAN programs will be presented in class and posted on the course web site
