InteractiveRoark'sFormulas™
Proven and PowerfulInteractive Roark’s Formulas has been thoroughly user–tested and in continuoususe since 1989. It includes interactive calculations for all cases and tables withaccompanying diagrams that help streamline the design process and reduce designiterations as well as the need for complicated finite element analysis. In addition,International System of Units (SI) and United States Customary Units (USCU)conversion is automatic with Interactive Roark’s Formulas, making model sharingeasier than ever.
The user–friendly menuing system lets you select a problem by chapter, table, andcase—exactly as it is in the book. However, here’s where the similarities end.Pre–formatted plots of deflection, stress, and bending moments let you refine thedesign like never before. What’s more, a powerful math engine with the uniqueability to solve for a variety of combinations of input and output variables—knownas backsolving—allows you to easily test what–if scenarios and optimize designswithout hours of tedious calculations or programming. Just point, click, and solve.
Interactive Roark’s Formulas at a Glance• Interactive Calculations—for all cases and tables• Dynamic Plot Annotations—for data analysis and visualization• Full Materials Database—for streamlined data entry• Automatic Unit Conversion—for model sharing flexibility• Report Wizard—for on–demand custom reporting• Solution Optimizer—for advanced control over constraints and bounds
Bottom Line: Interactive Roark’s Formulas gives youthe ability to tackle design challenges that wouldotherwise be too complicated or costly to attempt.
A Designer’s DreamInteractive Roark’s Formulas includes a number of built–in functions and ease of usefeatures like the Superposition Data Entry Wizard that allows multiple loads to behandled easily by automatically calculating and displaying plots of stress, deflection,and shear for the combined loads every step of the way. What used to take hoursnow takes a matter of minutes!
When first released in 1989, Roark’s Formulas for Stress and Strain co–author WarrenYoung called Interactive Roark’s Formulas “a designers dream.” In reality, it’s anindispensable tool for any designer, engineer, or technician that works with beams,columns, plates, rings, tanks, or pressure vessels.
Interactive Roark’s Formulas is available in a Standard and Premium edition thatincludes the Solution Optimizer, and supports Microsoft® Windows 2000 and XPplatforms.
The Ultimate Reference
Long considered the leading authority on structural element design and analysis, Roark’s Formulas for Stressand Strain has been helping engineers solve design problems for more than 60 years.
Universal Technical Systems, Inc. (UTS) takes it one step further with Interactive Roark’s Formulas—a fullyinteractive version of the landmark reference combined with powerful problem solving technology thatdramatically reduces design hours and production costs and speeds time to market. Imagine not just wordsand formulas on a page, but completely automated stress analysis of a comprehensive range of structuralcomponents—right on your desktop!
