Question

Im confused on how to go about this question. More specifically on what plane stress means in this case

1.2-13 Two steel rods are welded together (see figure);
the seam is oriented at angle 0 = 50°. The stresses on
the rotated element are o=10 ksi, 0 yl
and Txlyl
= -12 ksi,
%3D
= -5 ksi. Find the state of plane stress on
X1
the element if it is rotated clockwise to align the
axis with the longitudinal axis of the rods.
