Extracted text: 4. A wood post 12 in. by 12 in. is braced by four steel angles. The wood post and the pieces of angles are exactly the same length of 20 feet. The reinforced post carries a total compressive load of 200 kips. For steel: E = 29 x 10^3 ksi, for wood: Area = 0.938 sq. in., E= 1.9 x 1013 ksi a. Find the axial stress (in kips) in the steel. b. Find the axial stress in the wood. c. Find the deformation (in inches) if the length of the reinforced post is 12 ft.
