This looks like it would be useful capability. As far as I can tell I did not get a useable copy of the software. I did get a menu that allowed me to view the kinds of calculations that can be made, but I could not find a way to enter my own information. In general the software seemed to be missing one piece of capability that we were looking for. We want to know, for a particular design wind and wire cross section, how the change in radius and change in spring length for a particular applied torsion are ...

This seems like a nice spreadsheet although it's not quite what I was looking for. A bit more documentation and instructions would make it easier to use...

Hello, this calculator appears to be very useful, however I was looking for calculations on a spiral (like clock) spring loaded radially. Good luck with it and please let me know if you develop this capability.

springs 15 types Unfortunately the software does not handle helical compression springs with variable pitch. This would be a useful inclusion. I am especially interested in variable pitch conical compression springs. A help section that defines parameters would also be useful. For example, what is section 4.16, coil shift?

Design Engineer Thanks. Am eager to test the software.

How do I use it ? The plot of the calculations is given as a text file, in the form of a programer's code. But there is no where to be seen there - the answer to the ODE ! The interface is very unfriendly. The only screen that I mannage to see is a screen where it says : "Try me" or "Test me" or something ...

Match n Freq 5.12.4
Finds pole-zero locations 4 Transfer function Pulse shaping filter program that finds the pole-zero locations of a transfer function, H(s), for a matched filter. H(s) equals a -desired- signal (Yout) divided by a given input signal (Yin). Both Yout and Yin are functions of frequency. Group delay may also be calculated to compliment a given data set, thus, providing a flat group delay. Another improved productivity example do to using Calculus (level) programming.

Registration key Good dayI've downloaded the MATruss package, but did not receive a registration name or password. It is a trial version. Is there any chance you can help me with this. I gave me Mail address but still did not receive anything. Your urgency in this would be greatly appreciated. ThanksAnton
