If the weights retained on the 2.36 mm, 1.18 mm, 600 $\mu m$, and 300 $\mu m$ sieves are 30%, 35%, 15%, and 20%, respectively, of the total weight of an aggregate sample, then the fineness modulus of the sample is ........... (rounded off to 2 decimal places).

A steel beam supported by three parallel pin-jointed steel rods is shown in the figure. The moment of inertia of the beam is \( 8 \times 10^7 \, {mm}^4 \). Take modulus of elasticity of steel as 210 GPa. The beam is subjected to uniformly distributed load of 6.25 kN/m, including its self-weight. The axial force (in kN) in the centre rod CD is ......... (round off to one decimal place). 

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