A steel beam supporting loads from the floors slab as well as from wall is termed as

The problem of lateral buckling can arise only in those steel beams which have

Two steel plates each of width $$150$$ $$mm$$ and thickness $$10$$ $$mm$$ are connected with three $$20$$ $$mm$$ diameter rivets is placed in zig-zag pattern. The pitch of the rivet is $$75$$ $$mm$$ and gauge is $$60$$ $$mm.$$ If the allowable tensile stress is $$150$$ $$MPa,$$ the maximum tensile force that the joint can withstand is

In section, shear centre is a point through which, if the resultant load passes, the section will not be subjected to any
