An Input Form For The Mohr's Circle Program - HP 50g User Manual

To find the values of the stresses corresponding to a rotation of 35
of the stressed particle, we use:
$š
@TRACE @(x,y)@.
Next, press ™ until you read

An input form for the Mohr's circle program

For a fancier way to input data, we can replace sub-program INDAT, with the
following program that activates an input form:
« "MOHR'S CIRCLE" { { " x:" "Normal stress in x" 0 } {
" y:" "Normal stress in y" 0 } { " xy:" "Shear stress" 0}
} { } { 1 1 1 } { 1 1 1 }
With this program substitution, running @MOHRC will produce an input form as
shown next:
Press @@@OK@@@ to continue program execution. The result is the following figure:
