Correct answer is written below. Detailed and complete solution only. I will upvote, thank you. 

SITUATION 5: The rigid bar AB is supported by two rods made
of the same material. Neglect the weight of bar AB and the bar
is horizontal before the load P is applied. E = 70 x 10 psi.
1. Find the distance x (ft) that locates the position where
P must act if the bar is to remain horizontal.
2. If x = 5 ft, and P = 13 kips, calculate the deformation
(in) of B.
L=2ft
A-0.4 in.2
10ft
3. If x 5 ft, calculate the maximum value of P (kips) to limit the stress in both materials to 2.5 ksi.
ANSWERS: 2.5 ft; 0.017 in; 1 kip
L=3ft
A=0.2 in.2
B
