To find the values of the stresses corresponding to a rotation of 35

in the angle

of the stressed particle, we use:

$š Clear screen, show PICT in graphics screen

@TRACE @(x,y)@. To move cursor over the circle showing

Next, press ™ until you read

= 35. The corresponding coordinates are

(1.63E0, -1.05E1), i.e., at

= 1.63 kPa, and σ’

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” { { “σx:” “Normal stress in x” 0 } {

“σy:” “Normal stress in y” 0 } { “τxy:” “Shear stress” 0}

} { } { 1 1 1 } { 1 1 1 } INFORM DROP »

With this program substitution, running @MOHRC will produce an input form as

Press @@@OK@@@ to continue program execution. The result is the following figure:
