Question

I have been stuck on this problem for while thar area is 779.1 mm^2  sigma_x is 120.6497159 sigma_y is 0 and tau_xy is 0. Beta is 20 degrees

- X Incorrect. Use the shear stress transformation equation, Equation Tnt = - (x − σy) sin@cose + Txy(cos²0 — sin²0) Tnt = -(ox - σy)sincose + Txy (cos²0 - sin²0). The angle 00 shown in the figure above is equal in magnitude to the angle ßß given in the problem statement. Note that 00 turns clockwise from the xx axis, so when used in Equation Tnt = - (ox - oy) sin cose + Txy (cos²0 – sin²0) Tnt = − (0₁-0₂)sin@cose + Txy (cos²0 - sin²0), 00 is negative. Determine the shear stress parallel to the weld seams. Use the correct sign based on the sign convention for shear stress and consistent with the n - t coordinate system shown. Tnt = i -38.776 eTextbook and Media Hint B Save for Later MPa P Assistance Used Use the shear stress transformation equation, Equation T = -(ox-oy)sin@cose + Txy (cos²0 - sin²0).
