The testing, evaluation and refinement stage is an integral part of the engineering design process. This video investigates three real-world projects requiring different testing methods, uncovering why testing is crucial to achieve finished products that fit the brief. Engineering students will benefit from interviews with engineers who worked on the Deepsea Challenger life support sphere, the Morph Wheels foldable wheelchair wheel, and the Fliteboard electric hydrofoil.

A critical aspect of design is the selection of materials to make a product. Physical and chemical properties, cost and availability, and social, ethical and environmental impacts of materials are all important considerations. This video explores criteria for selecting the best materials for engineering projects by following three exciting case studies: the Deepsea Challenger life support sphere, Morph Wheels foldable wheelchair wheel, and Fliteboard electric hydrofoil.

Engineers can face many design challenges when undertaking a project. Identifying problems is the crucial first step in the process of designing solutions. This video looks at some unique challenges and the approaches that real-world companies take to tackle them in three exciting case studies: the Deepsea Challenger life support sphere, Morph Wheels foldable wheelchair wheel, and Fliteboard electric hydrofoil.

Scientists and engineers have made great strides in recent years with prosthetics and orthotics. In this programme we discuss how designers are striving to simulate the anatomy and physiology of missing limbs. Though some prosthetics are simple and minimally functional, others are complex bionic artificial limbs with improved designs, using advanced hydraulics, lightweight materials such as carbon fibre, and computer microprocessors and sensors.

This video presents the potential hazards and the correct use of, angle grinders, jack-hammers, circular saws, and power drills. Using examples and commentary from a Master Builder, a practical guide of how to use each power tool is demonstrated and explained. Units of Competency: CPCCOHS1001A - Work safely in the construction industry. CPCPCM2043A - Carry out WHS requirements. Warning: this program contains graphic imagery that some viewers may find disturbing. Show Less
This video looks at the risks of working with electricity, recognising where hazards may come from and how the hazards can be identified. We examine the factors that should be considered when undertaking a risk assessment such as work practices, availability of test instructions and the types of equipment being used. Units of Competency: CPCPCM2043A - Carry out WHS requirements CPCCOHS2001A - Apply OHS requirements, policies and procedures in the construction industry UETTDRRF01B - Apply ESI safety rules, codes of practice and procedures for work on or near electrical apparatus UEENEEE033B - Document occupational hazards and risks in electrical work UETTDREL16A - Working safely near live electrical apparatus CPCCOHS1001A - Work safely in the construction industry.

This programme shows viewers the safe way welders work with fire, gas, and molten metal as it profiles the tools used by welders to perform a variety of tasks. Specific tools and equipment for OFW, GMAW, GTAW, and SMAW are spotlighted, along with a variety of general tools and safety items. Show Less
This is a comprehensive and accessible introduction to the techniques and business of commercial printing. It looks at covering, binding, finishing, and how to create work that satisfies the client's commercial and aesthetic needs.
This programme sets out in clear, linear fashion how to take care of hand tools and how to maintain their efficiency. Addressing one tool at a time, the program includes demonstrations of sharpening a chisel, a plane, a cross-cut saw, a ripsaw, and more. The importance of maintaining a sharp edge on cutting tools is explained, including the relationship to safety. Different kinds of sharpening stones and their applications are detailed as well as proper technique at the grinding wheel. Terms are clarified as they are introduced, including honing, grinding, wire edge (burr), flatting, stropping, etc. As well as the more obvious tools (saws, chisels, planes), the program devotes time to others including scrapers, lathe tools, drill bits, marking tools even clamps and the woodworker's vice.

This program looks at how physics of sound is applied in a real sound recording studio. It is a unique window into the world of the music industry through the eyes of physics. There are many aspects to the physics of sound that a recording engineer has to take into account when recording sound. From room characteristics to frequency response, microphone characteristics to equalisation, recording engineers work with the full demands of the physics of sound. Show Less
This program looks at how electricity is distributed from power stations to the end user. We look at: - Line loss. - Transformers: how they reduce line loss. - The high voltage network. - Connecting the user. - The purchasing of power.
Machines change force and distance but the work done is constant. We look at machines from the perspective of W=FD including: * Inclined Planes * Pulleys * Levers * Gears as circular levers, belt pulleys * Hydraulic pistons.
