Solving Equations - Problems

As you work on the problems in this section, try to use all the Mathcad features you have learned so far and practice the problem-solving strategies we have advised along the way. We give a brief review below.

Remember to assign the information in the question to variables, with brief phrases for explanation. Then you can investigate the problem and generate ideas that will lead towards a solution.

You may want to start by getting a feel for the concepts of the problem in everyday terms and give a rough estimate of the answer you would expect (how much?). Then think about the general principles at work, instead of trying to rush to the answer. If you are really stuck, you could use dimensional analysis to work backwards from the dimensions you expect the answer to have.
