    Mathematical Error or Units

    >12 is just a constant and the units of I{k} must be in^4 or ft^4 (In the attached worksheet, it was my mistake I should have written in^4 (highlighted in green)) I should get I.k or I.c value 2264 in^4 or 0.109 ft^4 not 3.5*10^4 in^4 or 1.7 ft^4 as calculated by mathcad Thanks..

    Reddefining a Variable

    For some reaon it was not displaying the value of Fy after redefining the variable. I was been told by my senior (who initiated me to use MATHCAD)that its always good to write in one text block so that its easy to copy paste in report or create reports. and everything lines up perfectly.. I...

    SACS Analysis for tower modelled as a 2d frame and truss

    Iam not familiar with dynamics but I will suggest you to try all joints as master (222222) except boundary joints which should be either pinned/fixed. For extracting mode shapes all the main joints should be assigned as master. Thanks.
