Q 1. A light beam AG 12m in length is loaded and supported as follows:

         -At end A is a concentrated load of 101.937 t.

        -8m length of the beam from end G is loaded uniformly with load of 40.775 t/m.

        -End A is  supported by a knife edge.

        -End G is evenly supported over a length of 4m.

        Draw the SF& BM curves of the beam calculating values every 2m of length.

Q.2 M.V. Hindship in DW of RD 1.005 is at a draft of forward 7.60m, Aft 7.95m. she has to

        Load 450t of cargo, where , with respect to AP should this cargo be loaded, so as to complete

        The loading with a trim of 1.0m by stem.

Q3 a) A ship at a draft of 7.0 m, KG 6.5 m, KM 7.0m turns in a circle of radius 500m at a speed

             Of 12 knots. Calculate the heel produced.

       b) When a mass of 25 Toners is shifted 15m transversely across the deck of a ship of 8000
