The calculation is intended for the purposes of geometric and strength designs of metal springs of various types and designs (15 types), subjected to static or cyclic loads. Application is developed in MS Excel, is multi-language and supports Imperial and Metric units. Is based on ANSI, ISO and DIN standards.

Universal tool for statistical analysis and modeling experimental and market data. Support import data from text and database files; paste; extraction from pictures.
Statistical schemes cover all major statistical problems ? building histograms including conditional; curve and surface fitting; multivariate approximation and near neighbors estimation; peaks revealing; scoring market data.
Create instant report ready presentation of the results.

Excel add-in with eleven powerful worksheet functions for 1, 2 and 3 variable lookup and interpolation. Interpolation modes include: closest-value, linear, piecewise parabolic or hyperbolic, cubic spline and polynomial up to 20th order. Handles tables with missing data.
Fits polynomial curves through a set of X-Y points, returns table of polynomial coefficients and finds the best fit curve.
Includes online help and examples for Windows and Mac.

Mechanics is a Virtual Laboratory of Mechanics. An Intuitively Easy-To-Use collection of -at least- 51 interactive Mechanics simulation modules that allow the user to simulate and visualize experiments.

A Virtual Laboratory mainly a t the University level, however, High Schools with ambitious programs and Colleges may find Visual Mechanics very useful for their courses.
