Consider the frame shown in the figure under the loading of $100 \mathrm{kN} . \mathrm{m}$ couples at the joints B and G. Considering only the effects of flexural deformations, which of the following statements is/are true:

In the rigid-jointed frame shown in the figure, the distribution factor of the member $A D$ is closest to

Consider the rigid bar ABC supported by the pin-jointed links BD and CE and subjected to a load $P$ at the end $A$, as shown in the figure. The axial rigidities of $B D$ and $C E$ are 22500 kN and 15000 kN , respectively. If CE elongates by 5 mm due to the load P , the magnitude of the downward deflection (in mm ) of the end $A$ would be _________ (rounded off to the nearest integer).

Consider the beam section shown in the figure, with $y$ indicating the depth of neutral axis (NA). The section is only subjected to an increasing bending moment. It is given that $y=18.75 \mathrm{~mm}$, when the section has not yielded at the top and bottom fibres. Further, $y$ decreases to 5 mm , when the entire section has yielded. The shape factor of the section is ________ (rounded off to 2 decimal places).
