In the design of lacing system for a, built-up steel column, the maximum allowable slenderness ratio of lacing bar is

Group-$${\rm I}$$ contains some elements in design of a simply supported plate girder and Group-$${\rm II}$$ gives some qualitative locations on the girder. Match the items of two lists as per good design practice and relevant codal provisions.

Group $${\rm I}$$
$$P.$$$$\,\,\,\,\,\,$$ flange splice
$$Q.$$$$\,\,\,\,\,\,$$ web splice
$$R.$$$$\,\,\,\,\,\,$$ bearing stiffeners
$$S.$$$$\,\,\,\,\,\,$$ horizontal stiffener

Group $${\rm II}$$
$$1.$$$$\,\,\,\,\,\,$$ at supports (minimum)
$$2.$$ $$\,\,\,\,\,\,$$ away from center of span
$$3.$$$$\,\,\,\,\,\,$$ away from support
$$4.$$$$\,\,\,\,\,\,$$ in the middle of span
$$5.$$$$\,\,\,\,\,\,$$ longitudinally some where in the compression flange

A curved number with a straight vertical leg is carrying a vertical load at $$Z,$$ as shown in the figure. The stress resultants in the $$XY$$ segment are. Bending movement, shear force and axial force

List - $${\rm I}$$ shows different loads acting on a beam and list - $${\rm II}$$ shows different bending moment distributions. Match the load with the corresponding bending moment diagram.
