The planar structure RST shown in the figure is roller-supported at S and pin-supported at R. Members RS and ST have uniform flexural rigidity (EI) and S is a rigid joint. Consider only bending deformation and neglect effects of self-weight and axial stiffening.
When the structure is subjected to a concentrated horizontal load P at the end T, the magnitude of rotation at the support R, is
A
PL3 / 12EI
B
PL2 / 12EI
C
PL2 / 6EI
D
PL / 6EI

Correct : b
