Question

~The kinematic indeterminacy of the plane structure considering the members to be inextensible is

• A. 6

Answer 1

The correct option is A 6

The possible deformations are

${\theta }_A,{\theta }_{B_1}\left(forbeamABC\right),$
${\theta }_{B_2}\left(formemberBD\right),$
$\Delta y_C,{\theta }_C,{\theta }_D$
Hence DOF of the plane structure considering inextensibility is '6'
