Wood beam has a couple (50+x) applied at A, uniform distribute force 15 kips/ft between BC and concentrated force 20 kips at C. If the allowable tensile strength is (10+x) ksi, and the allowable compressive stress is –(20+x) ksi. (a) What should be the minimum height h of the cross section? (b) Based on the minimum height h calculated in a, what is the minimum radius of curvature of the beam? Please enter the minimum radius of curvature in the box.
