An element in plane stress (see figure) is subjected to stresses x = 2,340 kPa, oy = 488 kPa, and xy = -465 kPa. (Consider only the in-plane stresses - the stresses in the x-y-plane). Ⓡ (a) Determine the principal stresses (in kPa) and angles of the principle planes (in degrees counterclockwise from the +x-axis). (Use the sign convention for stresses acting on inclined sections.) %1 %2 p1 ºp2 = =1036.195 X Your response differs from the correct answer by more than 10%. Double check your calculations. kPa = 0 0₂ Tmax normal = kPa Show them on a sketch of a properly oriented element. (Submit a file with a maximum size of 1 MB.

(Enter your stresses in kPa and your angle in degrees counterclockwise from the +x-axis. Enter the magnitude of the maximum shear stress. For the normal stress, use the sign convention for stresses acting on inclined sections.) kPa kPa counterclockwise from the +x-axis counterclockwise from the +x-axis Show them on a sketch of a properly oriented element.
