3.2.4 - 3.2.7 Young's Modulus IB DT HL

A3.2 Introduction to Structural Systems Theory IB DP DT New Spec

In this series of lessons, students gain an understanding of the HL topic A3.2, Introduction to Structural Systems, theory content in the IB DP Design and Technology course. Lessons include objectives, keywords, engaging activities, videos and real-world examples that students can relate to. Lessons culminate in a task where students consolidate and apply the key theory that they have learnt so that they are prepared for any IB DP assessments. Lessons cover the entirety of what students need to learn for this topic: 3.1.6 Mechanical properties 3.2.4 Forces 3.2.1 Structures are ubiquitous in nature and the built environment. 3.2.2 Structures can be classified in different ways. 3.2.3 Structures are often comprised of multiple parts. 3.2.4 Static and dynamic forces can be identified according to how they act on a structure. 3.2.5 In structures, it is important to know how and when an object or material will stretch, bend or break. 3.2.6 Materials with differing Young’s Modulus are chosen for specific applications. 3.2.7 When forces on a structure are in equilibrium, the structure is stable. 3.2.8 The overall design of a structure can be improved by applying strengthening techniques. 3.2.9 Structures are typically designed with a safety factor (SF) in case of overloading. 3.2.10 Structures are typically designed to withstand higher loads than required. Lessons should ideally be taught in order. If you enjoyed this project/scheme of work. Please visit my shop, where there is a range of creative and engaging design and engineering projects.
