STRESS Transformation Calculator (Plane Stress)    
by: Dominic J. Dal Bello

1. Enter the original STRESSES on the element:
     s_x =    s_y =    t_xy =  

2. Enter the counterclockwise (positive) rotation of the element:
            q (degrees) = ° (enter a number even if only calculating
                                                                          maximum values)

3. 

Stresses in rotated system (rotated q from original axis):

   s_x' =    s_y' =    t_x'y' =

Note: The angles listed below correspond to vectors (rotated q from the x-axis) that are normal to the faces on which the stresses act. Angles in degrees.

Principal Stresses
   Max. Principal Stress:  s_I =   at   q_I = °
   Min. Principal Stress:   s_II =  at  q_II = °

Maximum In-Plane Shear Stress
   Max. (Pos.) Shear Stress:   t =  at q_s,1 = °
   Max. (Neg.) Shear Stress:      t =  at q_s,2 = °

   Normal Stress on both faces:   s_s=
