Construction and Mechanical Technologies
Construction and Mechanical technologies focus on knowledge and skills associated with working resistant materials and textiles to create technological outcomes, understanding structures and machines, and modifying and creating patterns. Students develop and understandings and skills related to constructing a quality outcome.
The components of Construction and Mechanical Technologies are:
Construct a Resistant Materials Product
Construct a resistant material’s product requires students to implement procedures and tests to make specified products using resistant materials.
Construct a Textiles Product
Construct a textile material’s product requires students to implement techniques and procedures and tests to make specified products using textile materials.
Knowledge of Resistant Materials Construction
Resistant Materials refer to a group of materials that are grouped together because they show certain common characteristics. These characteristics include: tensile strength, compressive resistance, hardness, malleability, ductility, elasticity, grain. Such materials are broadly categorised as wood, metal, ceramics, plastics, glass and their composites. Particular resistant materials exhibit characteristics to a greater or lesser extent. Resistant materials are often sub categorised. For example hardwood and softwood; thermosetting and thermoplastics, alloys and pure metals.
Construct a Specified Product Using CNC Machines
Construct a specified product requires students to implement procedures and tests to make specified products using Computer Numerical Controlled (CNC) machines.
Initially students learn to perform a sequence of techniques and tests to make specified products using CNC machines that meet specifications. Students should progress to performing complex procedures, which incorporate the use of CNC machines to make specified products that meets specifications.
Knowledge of Textiles Construction
Textile Materials refer to a group of materials that are grouped together because they show certain common characteristics. These materials include but are not limited to: natural and synthetic fibres, yarns, knits and woven fabrics.
Knowledge of Structures
A structure refers to framework that is used to support a load(s). A framework is comprised of structural members that are assembled using pin or fixed joints. The integrity of a framework is reliant on the strength, weight, material and profile of its structural members; the combination and means of joining structural members; and the safety factors applied to the structure.
Knowledge of Machines
Machines consist of fixed and moving parts that modify mechanical energy and transmit it in a more useful form. A simple machine; such as a lever, a pulley, or an inclined plane; alters the magnitude or direction, or both, of an applied force. Complex machines have internal energy systems; such as electric motors, steam engines, turbines, combustion engines, solar energy systems, nuclear systems; that combine with levers, inclined planes and/or screws to enable the machine to perform their intended function/s.
Pattern making includes stills in pattern adaptation and pattern drafting. Pattern drafting requires a pattern block or working drawing to be established by using key measurements and using these to develop a pattern which interprets a garments or items design including its special features. Patterns are tested using toiles and mock-ups to ensure that pattern pieces correctly interpret a design and its special features.
Create an applied design
Implement procedures to create an applied design for a specified product requires students to learn how applied designs and complex procedures can be used to create specified products.
