Consider the following two statements related to structural steel design, and identify whether they are True or FALSE.

$${\rm I}.\,\,\,\,\,\,$$ The Euler buckling load of a slender steel column depends on the yield strength of steel.
$${\rm II}.\,\,\,\,\,\,$$ In the design of laced column, the maximum spacing of the lacing does not depend on the slenderness of column as a whole.

Identify the most efficient butt joint (with double cover plates) for a plate in tension from the patterns (plan views) shown below, each comprising $$6$$ identical bolts with the same pitch and gauge.

The bending moment (in $$kN$$-$$m$$ units) at the mid-span location $$X$$ in the beam with overhangs shown below is equal

The degree of static indeterminacy, $${N_s}$$ and the degree of kinematic indeterminacy, $${N_k}$$ for the plane frame shown below, assuming axial deformations to be negligible, are given by:
