436-202 Mechanics 1

Students will be expected to be familiar with material covered in 436-101 Engineering Mechanics and Materials and 100-leve1 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; basic properties of beams, symmetric bending; flexure by McAulay's method, superposition, indeterminacy; and short and long columns, inelastic behaviour.

Unit 2, Dynamics of Machines: On completion of this unit students should understand how to perform kinematic and dynamic analysis of planar mechanisms using analytical, numerical and/or graphical methods and be proficient at identifying, modelling and analysing vibrating single-degree-of-freedom systems.

Topics covered include structural analysis and synthesis; mobility, velocity and acceleration diagrams; analytical kinematics of planar mechanisms; forces in machine members; dynamic reactions in joints; dynamics of mechanism input links, equation of motion, balancing; equations of motion of undamped, damped, free and forced vibration, kinematic and dynamic excitation; natural frequency, critical speed, resonance, transfer functions; application of integral transforms; and applications in machine design.

Laboratory and tutorial work assignments not exceeding 20 pages or equivalent; one examination not exceeding three hours. Students will be notified of the weighting of assessment components at the beginning of semester.
