D Structures and Mechanisms

• D1 Relating Science and Technology to Our Changing World

  • D1.1 evaluate environmental, social, and economic factors that should be considered when designing and building structures to meet specific needs for individuals and communities

  • D1.2 evaluate the impact of the ergonomic design of various tools, objects, and work spaces on a user's health, safety, and ability to work efficiently, and use this information to describe changes that could be made in their own spaces and activities

• D2 Exploring and Understanding Concepts

  • D2.1 classify structures as solid structures, frame structures, or shell structures

  • D2.2 describe ways in which the centre of gravity of a structure affects the structure's stability

  • D2.3 identify the magnitude, direction, point of application, and plane of application of the forces applied to a structure

  • D2.4 describe the role of symmetry in structures, and identify instances of symmetry in various structures

  • D2.5 describe factors that can cause a structure to fail

  • D2.6 identify the factors that determine the suitability of materials for use in manufacturing a product or constructing a structure

  • D2.7 describe methods engineers and other professionals use to assess, improve, and maintain the safety of structures
