OverviewDescriptionThis subject builds on and brings together the concepts introduced in the Mathematical and Physical Modelling subjects and in Introduction to Mechanical and Mechatronics Engineering. It is intended to provide students with a comprehensive overview of elementary mechanics and lay the basis for further work in this area in later subjects. In particular, material discussed in this subject is taken further in Machine Dynamics and Mechanics of Solids subjects in subsequent stages.Newtonian mechanics depends on the development of a series of increasingly complex models based on Newton?s Laws of Motion. The purpose of this modelling concept is to set up an orderly development that is conducive to mathematical analysis. The methodology relies on diagrammatically isolating a physical entity (or body) from all constraints or contacts with other bodies and replacing these contacts with external forces. This relies on discriminating between what are defined as internal and external forces. The mechanically isolated body is referred to as a free body diagram. It requires a graphical, diagrammatic or visual approach to problem analysis, unlike other analytical systems, which rely on more sophisticated mathematical analysis.The topics discussed in this subject include equilibrium in 2D plane and 3D space, force vectors, force system resultants, analysis of pin-connected trusses, characteristics of dry friction, equilibrium of rigid bodies subjected to frictional force, shear force and bending moment diagrams, kinematics and kinetics of a particle, rectilinear kinemtatics, curvilinear motion, force and acceleration, work and energy, impulse and momentum, and the relationships between them. These comprise the basis of a comprehensive course in Newtonian mechanics.Subject objectivesUpon successful completion of this subject students should be able to:1. Apply Newtonian mechanics, which is one of the fundamental sciences underlying engineering practice;2. Draw the Free-Body Diagrams, evaluate the force systems, and understand the modelling concept, as applied to Newtonian mechanics;3. Apply principles of particle mechanics and its limitations;4. Apply basic engineering concepts such as equilibrium, force and acceleration, work, energy and power, impulse and momentum, and the relationships between them;5. Apply the analytical skills in statics, dynamics and mechanics;6. Apply Free-Body-Diagrams, frames and machines, structural analysis, dry friction and frictional force, stress resultants, kinematics and dynamics of plane motion, work, energy and power, linear impulse and momentum, conservation of momentum, impact.This subject also contributes specifically to the development of the following course intended learning outcomes:Apply systems thinking to understand complex system behaviour including interactions between components and with other systems (social, cultural, legislative, environmental, business etc.) [EA Stage 1 Competency: 1.5 ] (A.5)Identify and apply relevant problem solving methodologies [EA Stage 1 Competency:1.1, 2.1, 2.2, 2.3] (B.1)Synthesise alternative/innovative solutions, concepts and procedures [EA Stage 1 Competency: 1.1, 3.3] (B.3)Develop models using appropriate tools such as computer software, laboratory equipment and other devices [EA Stage 1 Competency: 2.2,2.3, 2.4] (C.2)Evaluate model applicability, accuracy and limitations [EA Stage 1 Competency: 2.1,2.2] (C.3)Communicate effectively in ways appropriate to the discipline, audience and purpose [EA Stage 1 Competency: 3.2] (E.1)Teaching and learning strategiesThe teaching and learning approaches consist of a series of lectures and tutorials with emphasis on self-study. The students will be guided and assisted to reach the learning objectives a series of milestones strategically set throughout the semester. Six quizzes will be arranged during the semester to consolidate students? learning.This subject includes one lecture session of 1.5 hours and one tutorial session of 1.5 hours per week throughout the semester.This subject is a typical 6cp subject and therefore assumes a total time commitment (including class time) of approximately 150 hours, i.e. roughly 10 hours per week, for an average student aiming to pass the subject.In each topic, students will be given a set of engineering mechanics problems (including problems discussed in lectures and tutorials and problems for student self-learning) with answers. Those problems and their answers will be made available on UTS-Online/handouts. Students are expected to use these problems to help them learn engineering mechanics and kinematics.ContentThe topics to be covered in 14 lectures are:? Force vectors and force system resultants;? Equilibrium of rigid bodies in 2D and 3D;? Free-body diagrams;? Two- and three-force members;? Frames and machines;? Pin-connected trusses. Method of Joints and Method of Sections;?
