| Brief Handbook Description: | The unit aims to provide students with an understanding of and competence in solving statics and introductory dynamics problems in engineering. Tutorial sessions will help students to improve their group work and problem solving skills, and gain competency in extracting a simplified version of a problem from a complex situation. Emphasis is placed on the ability to work in 3D as well as 2D, including the 2D and 3D visualisation of structures and structural components, and the vectorial 2D and 3D representations of spatial points, forces and moments. Introduction to kinematics and dynamics topics includes position, velocity and acceleration of a point; relative motion, force and acceleration, momentum, collisions and energy methods. |
| Assumed Knowledge: | None. |

| Assessment Description: |
* indicates an assessment must be repeated if a student misses it due to special consideration. Long Quiz 1: Held 4:15-5:30 PM, Friday, of Week 4, at a venue indicated in your Timetable. Closed book and based on the material covered to date. Long Quiz 2: Held 4:05-6:00 PM, Friday, of Week 9, at a venue indicated in your Timetable. Closed book and based on the material covered to date. Long Quiz 3: Held 4:05-6:00 PM, Friday, of Week 13, at a venue indicated in your Timetable. Closed book and based on the material covered to date. Assignment: Due on Friday of Week 11. Late assignment will receive a penalty of 10% per calendar day. Short Quizzes: Online short quizzes held weekly. There may be statistically defensible moderation when combining the marks from each component to ensure consistency of marking between markers, and alignment of final grades with unit outcomes. |
