Engineering: Bivariate Normal Probabilities in Engineering 
An extensive study was made of shear strength (x2) and weld diameter (x1) in an attempt to substitute a less expensive, nondestructive testing procedure for a destructive test. 


TK Solver 5.0 Equation Solving 101 
A single equation can do the work of n assignment statements. If a problem involves m independent equations, each with an average of n variables, you would need m*n assignment statements to cover all of the possible configurations of known and unknown variables. In TK Solver, you simply work with the m equations... 


TK Solver 5.0 Walk Through 
Explore the various features and capabilities in this easytofollow guide. Let's look at a simple example to see how TK works. 


TK Solver: Mathematical Modeling 
Mathematical models come in all shapes and sizes. They can be simple, like the geometry of a cone, or they may involve more sophisticated models for structural analysis, heat transfer, chemical engineering process design, or even economics. How does one proceed once one finds a math model? 


TK Solver: A Better Idea Whose Time Has Come 
A software program called TK Solver was first mentioned on the pages of BusinessWeek fifteen years ago (June 7, 1982). Today, after changing hands twice (first to Lotus in 1985 and then later that year to Universal Technical Systems, Inc. in Rockford, IL), TK Solver is one of the oldest (if not the oldest) personal computer software titles on the market. 


TK Solver: TK Versus Fortran 
Here is an excellent comparison of TK and FORTRAN. The example is obtained from the following textbook: Introduction to Computing by James, Smith and Wolford; HarperCollins. To build a better mouse trap, the value of spring stiffness (k) is to be determined from the following equation...
