Question 8: Prob. 2.2-14. The three-member frame structure in Fig. P2.2-14 is subjected to a downward vertical load P at pin C The pins at B, C, and D apply axial loads to members BD and CD, whose cross-sectional areas are A1 = 0.5 in^2 and A2 = 1.0 in^2, respectively. (a) If the axial stress in member BD is stress 1 =1200psi, what is the value of force P? (b) What is the corresponding axial stress, stress 2, in member CD? 12 in. -12 in. 9 t n. 9 in. A 32 in.
