Bottom Line: Roark’s Formulas for Excel gives you the ability to tackle design challenges that would otherwise be too complicated or costly to attempt
The first software edition of Roark’s Formulas, designed for TK Solver, was releasedby UTS in 1989, and was quickly received by consumers as a “design engineer’sdream,”as described by Professor Warren Young, the co–author of Roark’s Formulasfor Stress and Strain. Now UTS is taking the next step by making their popularsoftware available to Excel users.
Roark’s Formulas for Excel is available for Microsoft® Excel 2000 and higherrunning on Microsoft® Windows 2000 and XP platforms.
