Circuii Variabtes other t!?es of probleris you've successfully solved, following your intuition or hunches about how to proceed, and simply setting the prcblem aside temporadly and coming back to it later. 6. Test your sol tion. Ask yourself whether the solution you've obtained makes serlse. Does the magnitlde of the answer seem iea sonable? Is the solution physically realizable? You may want to go furtler and rework tle problem via an alternative method. Doing so will not only test the validity of your odghal answer, but will also help you develop your intuition about the most efficient solution methods for various kinds of problems. In the real \qorld, safety- cdtical designs are always checked by several iDdependent means. Getting into the habit ol checking your answeis will benefit you as a student and as a practicing engheer. These problem-solving steps cannot be used as a recipe to solve every prob lem in this or any other cource. You may need to skip, change the order of, oI elaborate on certail steps to solve a particular problem, Use these sleps

Unformatted text preview: as a guideline to develop a problem-solving style that works for you. 1.2 The International System of Units Engineen comparc theoretical results to experimental results and com-pare competing engine€rhg designs using quantitative measures. Modern engineering is a multidisciplinary profession in which teams of engineers work together on projects, and they can connnunicate their results in a meaningful way only if they all use the same units of measure. The Intemational System of Units (abbieviated SI) is used by aI the major engheering societies and most engifleers throughout the world;hence we use it in this book. Th€ SI units are based on seven d€lired quantities: . length ' fime . elect c current . thermod]'namic tempemture . amount of substance . luminous intensity :rI4*l:lrlillrri Qumtily Basic Unit Length Mass Tine Thermodynamic temperature AmouDt of substane kg K...
