NEED HELP ASAP!! Given values are in the picture
A steel post (E=30x10^6 psi) having thickness 1/8 in. and height l=70 in supports a stop sign (see the figure: s=11 in. ). The height of the post L is measured from the base to the centroid of the sign. The stop sign is subjected to wind pressure p=17 lb/ft^2 normal to its surface. Assume that the post is fixed at its base.

(a) What is the resultant load on the sign? [ ]. Round your answer to one decimal place.

(b) What is the maximum bending stress in the post? Round your answer to one decimal place.

(a) What is the resultant load on the sign? [ n = 8]. Round your answer to one decimal place.
F =
lb
(b) What is the maximum bending stress omax in the post? Round your answer to one decimal place.
Omax =
