Circulo de Mohr 2D 1.1 - detailed information

Circulo de Mohr 2D

Description: In two dimensions, determines the maximum and minimum tension, from two measurements of the normal and tangential tension on two right angles.

Description (2): En dos dimensiones, permite determinar la tensión máxima y mínima, a partir de dos mediciones de la tensión normal y tangencial sobre dos ángulos que forman 90º.

I ran into issues using the following values:
σx=40
σy=-60
τxy=-30

My angle reading was -1774.09 Degrees for 2θ with these values whereas it should be 30.963 Degrees.

I solved this by replacing lines 64-68 which had:
ANG1:=90*3.14159265359/(180);
ELSE
ANG1:=atan(2*(C)/(A-B));
END;
ANG:=(ANG1)*180/3.14159265359;

To:
ANG1:=90*(3.14159265359/180);
ELSE
ANG:=atan(2*(C)/(B-A));
END;
ANG1:=(ANG)*(3.14159265359/180);

With that code, I now get the correct value with all the values I test it with.

I am not sure if something happened when I downloaded the code that made it incorrect, or if I managed to find a mistake.

I hope this helps, and thank you for the very useful program!
