6.A beam ABC rests on simple supports at A and B with BC as an overhang. D is centre of span AB. If in the first case a concentrated load P acts at C while in the second case load P acts at D, then the

7.A cantilever beam carries a uniformly distributed load from fixed end to the centre of the beam in the first case and a uniformly distributed load of same inten�sity from centre of the beam to the free end in the second case. The ratio of deflections in the two cases is

8.A beam of overall length / rests on two simple supports with equal overhangs on both sides. Two equal loads act at the free ends. If the deflection at the centre of the beam is the same as at either end, then the length of either overhang is

9.Slenderness ratio of a 5 m long column hinged at both ends and having a circular cross-section with diameter 160 mm is

10.The portion, which should be removed from top and bottom of a circular cross section of diameter d in order to obtain maximum section modulus, is
