Paper Description

Edit Paper Description Content

Free body diagrams, a fundamental tool for Engineers, are used extensively in the paper. The concepts of equilibrium of rigid bodies is introduced and equilibrium analysis is carried out on structures, such as trusses, and mechanisms, such as lifts. Equilibrium equations are used to calculate forces due to applied loads are covered in statics. In the dynamics section of the paper the kinematic relationships (relationship between displacement, velocity and acceleration and the relationship between forces and acceleration (Newton's laws of motion)) as well as energy methods are covered.

Paper Structure

Edit Paper Structure Content

This paper has four lecture slots per week. Each lecture is broken into short 'theory' presentations followed by example problems demonstrating application of that theory. Students should attend one tutorial per week and two guided practical labs support learning earlier in the semester. Tutorials will help students use this knowledge in assignments and practical labs will see the implementation and advancement of the understanding of the topics. After teaching recess students will undertake a group project that further develops understanding and application of knowledge to a complex problem. Note that two textbooks by R. C. Hibbeler are recommended for this paper.

The syllabus for the tests may include material that is covered up to and including the week before the test. The format will be discussed in class prior to the tests.

Tutorial assignments and practical labs form an important part of the paper, they allow you to practice important concepts and therefore help you cement your knowledge and prepare for tests.

Group project report facilitates the development of technical writing and enhance the communication skills.
