2. what is the solution for this answer?
Transcribed Image Text:A beam with a Z cross-section is subjected to a
moment M, which has a magnitude of 20 kip -
in. The resisting moment Mr on the cross-
section makes an angle a = 36.870 with the =-
axis. The moments of inertia and product of
inertia for the cross section are = 8.83 in, 1₂
= 25.4 in4 and Iyz = 11.3 in4. Determine the
orientation of the neutral axis in degrees.
Note: Write answer in 2 decimal places.
