How do you land a rover on Mars, resolve a perpetual traffic jam or save a herd of caribou from potential extinction? Ask an engineer Author Shannon Hunt presents nine real-life problems for which engineers designed inventive (and even crazy ) solutions. Each was solved using a different field of engineering --- from aerospace and mechanical to the new field of geomatics. A helpful seven-step flowchart of the engineering design process is also featured: define the problem, investigate the requirements, develop solutions, design a prototype, test it, improve it and share the idea. These steps...
