Calculate the angle of the neutral axis from the x-axis when the beam is loaded with a positive couple of 6kNm acting around the X-axis
i have calculated:
Ixx: 2854758.6 mm^4
Iyy: 1429034.6 mm^4
Ixy: -1143476 mm^4
The Attempt at a Solution
i know that to calculate the angle:
tanθ= - (IxxMy -IxyMx)/(IyyMx-IxyMy)
since i am confused with the statement "positive couple of 6kNm acting around the X-axis"
does that mean that Mx= 6KNm?
