    "Find" function outputs fractions

    OK, I switched back to the <CTRL>+= and it is solving with no units on output vector, due to the way I normalized the find function. Is this what you meant when you mentioned normalizing the find function ?

    &quot;Find&quot; function outputs fractions

    In the attachment I got rid of all symbolic + and inserted inital guesses for thr 6 unknowns above the "Given" section. I also attempted to normalize all the six variables in the Find function. Any idea what is causing the "a name is required error message and the cause of left side of four...

    &quot;Find&quot; function outputs fractions

    OK. I deleted all units and it still solves with same numerical outputs, except now there are no units. Do you still believe my use of the "find" function with symbolic = and no initial guess is errant?

    &quot;Find&quot; function outputs fractions

    I just placed "float,2" from the Symbolic toolbar right after the arrow head and it is giving me decimal soln. I definitely am interested to figure out if my program is FUBAR. Any feedback is certainly valued. Thanks

    &quot;Find&quot; function outputs fractions

    -It is odd that you see so many flaws in the program because when I copy-and-paste the ridiculously long fraction outputs into Matlab and solve they are very realistic values for my application...except they output as ridic fractions. I'm certainly not discarding your comments because you are...

    &quot;Find&quot; function outputs fractions

    Thanks. See attachment. I'm fairly new to MathCad. Where do you suggest I place the word, "float"? http://files.engineering.com/getfile.aspx?folder=aab7d2b9-bb1a-47c5-91d3-b9c5e2551707&file=psot_11MAY2010.xmcd

    poisson ratio polyurethane moldings

    I tried talking to the material manufacturer, but the part that I am analyzing was made in the early-mid 80's and the company is unable to locate and provide the material data sheets. I understand the creep-rate effects for a constant load, but for a one-time impulse-loading situation it...

    poisson ratio polyurethane moldings

    Anyone know what poisson ratio value range I should be using for FEA purposes? Cannot find on efunda, etc. mil-m-24041c Thanks
