...think of their driving as safe, but most drivers have performed an overtaking or other manoeuvre which, in retrospect, would be considered ‘risky’. This section investigates how engineers can identify, assess and manage risks, and looks at what part they play in this process...Assessing risk in engineering, work and life: 1.1 Engineers and risk - The role of the...

...think that the root of this paradox is that the word is used both when we identify a need – the first link in the problem-solving chain – and when we undertake the process of meeting that need. It is the identification of the need and the realisation that it is real and must be met that creates the anxiety and the negative feelings ('Houston, we have a problem …')....

...Think about the sensing–logic–actuation cycle for the Oxboard transporter system. The board has sensors to detect the way the rider moves his feet and body. It uses logic to compute all the complicated forces associated with the motion; based on that information, it controls the two actuators (motor-driven wheels) to transport the rider in his desired direction. SAQ 1...

...system or a car radio rather than in a concert hall. In this case your music is relayed to you via various technological devices; well before the music reaches a compact disc (CD) or radio it will have been manipulated in various way using studio devices for recording, mixing and mastering. From the traditional acoustic instruments to the modern computer-based sampler or...

...thinking about yourself and others in a different way. This runs straight into the obstacle of the deeply ingrained habits that we all have in thinking in this area. I suggest that you adopt a quite moderate aim at first and try out one or, at most, two of the ideas presented. Choose the idea that seems to you most attractive, for whatever reason, and decide upon some...

...systems move through, or heating systems fail. Moving around is not necessarily any better, and can expose us to even wider ranges of temperature. An airliner may leave the ground where the temperature is in the high twenties Celsius and climb within minutes to a height where the outside temperature is minus fifty. It turns out that almost all materials properties change...

...systems (such as combining forces) using vectors perform simple algebraic procedures using vectors...Introducing vectors for engineering applications: Background - It is common in engineering for physical phenomena to be represented as vector fields. A vector field is a mathematical representation of a system that describes how a quantity, such as a force, changes over an...
