12/01/10 4 Problem Solving: Step 3 Construct the equations and solve Using theanalytical method you havechosen, arrive at a solution. Construct theequations carefully. Solvethe equations accurately. Present thesolution in a manner easily followed by other engineers. Show your work — Be neat. Provideenough information so that your solution can bechecked.
12/01/10 5 Problem Solving: Step 4 Verify the solution Check theaccuracy of thesolution to ensureyou have madeno errors. Does thesolution obey thelaws of physics? Ohm’s Law, Kirchhoff’s Laws, etc. Is the solution reasonable? Just because your calculator or your computer says so does not make it so… Do theunits makesense? HaveI really solved thespecified problem? If not, go back to step 2.
