Roark’s Formulas for Excel™
THE Ultimate REFERENCE
Long considered the most popular engineering handbook,
Roark’s Formulas for Stress and Strain has been helping engineers
solve design problems for more than 60 years. Universal Technical
Systems, Inc. (UTS) takes it one step further with Roark’s Formulas
for Excel, a fully interactive version of the landmark reference
combined with powerful problem solving technology that
dramatically reduces design hours, production costs, and speeds
time to market. Imagine not just words and formulas on a page,
but completely automated stress analysis of a comprehensive
range of structural components—right on your desktop! Since its first publication,
Roark is in constant use by mechanical, aerospace, civil, and many other types of
practicing engineers.

Proven and powerful
Roark’s Formulas for Stress and Strain has been thoroughly user–tested and in
continuous use since 1938. Roark's Formulas for Excel takes every table and case
from the 7th edition and makes it interactive, includes calculations for all cases and
tables with accompanying diagrams to help streamline the design process and
reduce design iterations, 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 Roark’s Formulas for Excel, making work
sharing among engineers easier than ever.The user–friendly menu system lets you
select a problem by chapter, table, and case—exactly as it is in the book. However,
here is where the similarities end.
Pre–formatted plots of deflection, stress, and bending moments let you refine the
design like never before.What’s more, a powerful math engine, with the unique
ability to solve for a variety of combinations of input and output variables (known
as backsolving), allows you to easily test “what–if” scenarios and optimize designs
without hours of tedious calculations or programming. Just point, click, and solve.

“This product is
The first software edition of Roark’s Formulas, designed for TK Solver, was released
by UTS in 1989, and was quickly received by consumers as a “design engineer’s
dream,” as described by Professor Warren Young, the co–author of Roark’s Formulas
for Stress and Strain. Now UTS is taking the next step by making their popular
software available to Excel users.
Roark’s Formulas for Excel is available for Microsoft® Excel 2000 and higher
running on Microsoft® Windows 2000 and XP platforms.
AWESOME!
Both the idea of implementing
Roark in Excel as well as how
UTS has done it are brilliant. No engineer
should be without it.”
