Figure 5.30 shows a river scow used to carry bulk materi- als. Assume that the scow's center of gravity is at its cen- troid and that it floats with 8.00 ft submerged. Determine the minimum width that will ensure stability in seawater.

A structure that has a triangular prismatic shape with 32 m length, 8 m width at the top and 5 m depth (total "height"). Assume that KG = 3.7 m.  What is GM when the construction floats on an "even keel" at draft T = 4 m.

Thank you for explaining in advance

When a bar of certain material 40mm square is subjected to an axial pull of 1,60,000N the extension on a gauge length of 200mm is 0.1mm and the decrease in each side of the square is 0.005mm. Calculate Young's modulus, Poisson's ratio. Shear modulus and bulk modulus for this material.
