Can you please solve this question?

.2-5 A hollow box beam is constructed with webs ouglas-fir plywood and flanges of pine, as shown in the figure in a cross-sectional view. The plywood is 24 mm thick and 300 mm wide; the flanges are 50 mm x 100 mm (actual size). The modulus of elastic- ity for the plywood is 11 GPa and for the pine is 8 GPa (a) If the allowable stresses are 14 MPa for the ply- wood and 12 MPa for the pine, find the allow able bending moment Max when the beam is bent about the z axis. (b) Repeat part (a) if the beam is now bent about its yax13. 50 mm 50 mm 50 rqm In 300 mm 24 mm100 mm PROBLEM 6.2-5
