| 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. |

| Roark's Formulas for Excel: Tutorial Problem 4 |
| Let’s switch from beams to plates. The next problem involves a flat annular plate with uniform annular line load, fixed on the outside and free in the center. Open the Roark’s Formulas for Excel Explorer and select a case from Plates Table... |

| Roark's Formulas for Excel: Tutorial Problem 5 |
| Continue with the annular plate from problem 4. To optimize the design, you would like to specify that the maximum deflection in the center be at most 10% of the plate thickness. You can use the Excel Solver to solve this problem. |

| 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; Harper-Collins. To build a better mouse trap, the value of spring stiffness (k) is to be determined from the following equation... |

| Roark's Formulas: Design of an I Beam |
| We assume that the I beam can be modeled as a cantilever beam fixed at the left end with a concentrated load at the end. Using the 7th edition of Roark's Formulas for Stress and Strain we will make use of two tables: The I beam cross section can be located in Appendix 1, Table A.1. Table 8.1, case 1a provides the shear, stress, and deflection formulas for our load and support condition. |
