436-202 Mechanics 1

Students will be expected to be familiar with material covered in 436-121 Introduction to Mechanical Engineering (prior to 2005 436-101 Engineering Mechanics and Materials) and 100-level mathematics.

Unit 1, Mechanics of Materials: On completion of this unit, students should be able to understand elastic and inelastic behaviour; and determine stresses and deformations in common structural elements.

Topics covered include two-dimensional stress and strain analysis; principal values; Mohr's circle; failure criteria; inelastic behaviour; basic properties of beams, symmetric bending; flexure by McAulay's method, superposition, indeterminacy; torsion of round bars; stresses in cylindrical pressure vessels; and the compressive behaviour of short and long columns.

Unit 2, Dynamics of Machines: On completion of this unit students should understand principles of the two-dimensional mechanics of a rigid body. Be able to carry out dynamic analysis of planar mechanical system.

Topics covered include dynamics of a particle in terms of inertial frames (work, kinetic energy, power, equations of motion), plane dynamics of a rigid body (kinetic energy, moments of inertia, equations of motion), dynamics of plane mechanisms (constraints, mobility, degrees of freedom, equations of motion).

• ability to apply knowledge of basic science and engineering fundamentals

• in-depth technical competence in at least one engineering discipline

• ability to undertake problem identification, formulation and solution

• expectation of the need to undertake lifelong learning, capacity to do so

• capacity for independent critical thought, rational inquiry and self-directed learning

• profound respect for truth and intellectual integrity, and for the ethics of scholarship

One 3-hour end of semester written examination (80%), together with three assignments not exceeding 1400 words each due throughout the semester (20%)
