Engineering Mechanics is concerned with the state of rest or motion of objects subject to the action of forces. The topic is divided into two parts: STATICS which considers the equilibrium of objects which are either at rest or move at a constant velocity, and DYNAMICS which deals with the motion and associated forces of accelerating bodies. The former is particularly applied to beams and truss structures. The latter includes a range of applications, such as car suspension systems, motion of a racing car, missiles, vibration isolation systems, and so on.
|Session||Second Sub Session||Credit Points||15 credits (7.5 ECTS credits)|
Newton's Second (F = ma) and Third Laws (equal and opposite reactions) are applied to the analysis of dynamic and static systems.
Stress, strain and elasticity will be introduced and applied, together with the principles of static equilibrium including the analysis of forces in statically determinate trusses, and of shear force and bending moment distribution in beams. The development of bending moment and shear force diagrams is introduced.
Kinematics and kinetics of rigid bodies moving in a single plane, including rectilinear and rotational motion, will be studied. Impulse/momentum and work/energy methods will be introduced. The motion of bodies of constant and variable mass acted upon by variable forces, including impulsive ones, is examined briefly. Practical case studies are used to illustrate the application of the concepts.Hands-on practical activities are used to enhance students learning. Students carry out laboratory experiments to determine the forces in a simply-supported beam and a two-member frame, and to analyse the motion of a projectile and pendulum. The experimental results are compared with the theoretical results and used to assess the limitations of the underpinning assumptions.
This is the total time spent in lectures, tutorials and other class teaching.
Two-hour written examination paper (80%)
4 Continuous Assessment Lab Activities (20%).
a) Assessment grade and feedback comments will be provided on laboratory report within one week of submitting the report.
b) Students can obtain feedback on their understanding of key aspects of the course at the weekly tutorial sessions.
c) Students requesting feedback on their exam performance should make an appointment with the course coordinator within two weeks of the publication of the exam results.
