ME1312Computer Aided Design4 ch (3C 3L)

Introduces the technology of 3D parametric geometric modeling to design and model mechanical engineering parts, assemblies and devices. Geometric variables and their interrelationships will be covered by projects involving the design of mechanical components, assemblies and machines to meet functional requirements. Manufacturing requirements including Geometric Dimensioning and Tolerancing. The use of the model for analysis, optimization and simulation will be stressed. Presentation of the model through engineering drawings and pictorial renderings. Animation of mechanisms. A comprehensive commercial CAD program will be utilized.

Prerequisite: ENGG 1003

ME3511Fluid Mechanics3 ch (3C)

The principles of fluid mechanics are introduced and methods are presented for the analysis of fluid motion in practical engineering problems. Specific topics include: fluid statics; integral balances of mass, momentum, angular momentum and energy; boundary layer theory and introduction to the Navier-Stokes equations; dimensional analysis; and liquid flow in piping networks with pumps and turbines. Pressure and flow measurement and experimental uncertainty.

Prerequisite: ME 2003 or APSC 1023.

Co-requisite: MATH 2513

ME4633 Vibration of Continuous Systems 3 ch (3C)

The free and forced vibration solutions for distributed parameter system models are covered in detail. Specific system models considered include strings/cables, rods, beams, plates, membranes and shells.

Prerequisite: ME 4613.

ME4860Senior Design Project8 ch (1C 2T 4L) [W]

A mechanical engineering design is developed and documented in the form of a technical report. Students normally work in approved teams. Industrial projects are developed in cooperation with industry and may require some period of time on site. University-based projects are developed in cooperation with university faculty. The first stage of this process involves definition of the project topic, background studies, and development of a conceptual design. An oral examination is conducted towards the end of the first term, and a written preliminary report is submitted. In the second term, a detailed design is prepared, the project is completed and orally examined, and a final report is submitted. One of the laboratory weekly hours is designated for a scheduled meeting with project advisor(s). Workshops involve practice exercises, relevant to student projects, on: problem definition and formulation, project planning, teamwork, information and communication; conceptual, parametric and configuration designs; and professional, environmental, social, human factors, and safety aspects of design.

Restricted to students who have completed at least 110 ch in their program.
Prerequisites: ME 3341 and ME 3345. Recommended prerequisite: ME 3524. Prerequisite for Mechatronics Option students: ME 4673.

Co-requisiteME 4861.
ME5122*Solid State Phenomena3 ch (3C)
Covers the fundamental aspects of crystallographic structure and their effects on the physical and mechanical properties of solids wiith emphasis on metallic materials with engineering applications. The importance of selecting alloying elements will be explored to optimize various properties such as but not limited to strength, ductility, fatigue, creep, corrosion, electrical, and magnetic. Construction and analysis of binary and ternary phase diagrams, which are critical in alloy design, complemented with computational thermodynamics will be covered. At the end of the course, the students are expected to understand the design and processing of commercial alloys.

Prerequisites: CHE 2501, ME 3222
ME5173*Advanced Kinematics of Manipulators4 ch (3C 3L*)

Various methods for solving the forward and inverse displacement problems are described. Particular emphasis is made on the use of screw theory for the derivation of the Jacobian matrix. The selection of alternate frames of reference for describing the Jacobian are also discussed. Methods used in the solution of the inverse displacement problem and the inverse and forward velocity problems for kinematically redundant manipulators are discussed. 

Prerequisite: ME 4173 or ME 5143. Recommended co-requisite: ME 2352.

ME5622*Human Factors Engineering 3 ch (2C 3L)

An interdisciplinary study of the interaction of humans and their workspace. Physiological principles of work and energy. Anthropometry. Biomechanics. The ergonomics of workspace and job design. Fatigue. Work/rest schedules and nutrition. The physiological and psychological effects of human noise, vibration, lighting, vision, and the workspace environment. Lab periods include seminars and practical design exercise applying human factors and ergonomic theory to workspace problems. 

Prerequisite: Restricted to students with at least 65 credit hours.

ME5673Acoustics3 ch (3C) [W]
Review of single degree of freedom oscillators, vibration of strings and bars. Topics include: the acoustic wave equation, transmission phenomena, pipe cavities and waveguides, resonators, ducts and filters, environmental acoustics and an introduction to aeroacoustics (time permitting).
