Transcribed Image Text: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 A = 0.5 in² and
A2 = 1.0 in², respectively. (a) If the axial stress in member
BD is o = 1200 psi, what is the value of force P? (b) What
is the corresponding axial stress, 02, in member CD?
