Structure 1 with Member BC of Length $L / 2$ /2 Has Force

question 21

Short Answer

Structure 1 with member BC of length $L / 2$ /2 has force $P_{1}$ applied at joint C. Structure 2 with member BC of length L has force $P_{2}$ applied at C.
Both structures have constant flexural rigidity EI. If the ratio of the
Applied forces $P_{1} / P_{2}=5 / 2$ , the ratio of the joint B rotations $\theta_{B 1} / \theta_{B 2}$ is
Approximately: (A) 1
(B) $5 / 4$
(C) $3 / 2$
(D) 2
