2. An open top box-shaped barge has the following dimensions: Length 50 m Breadth 14 m Depth 10 m The barge floats at a draught of 2156 m in dock water RD 1.007 when light. a) the light displacement of the barge

(b) The draught when floating in the light condition in salt water RD 1.025.

(c) the minimum weight of evenly distributed cargo required to sink the bange by a further 0.44 m in salt water.

If you were designing a bumper for a car, would you prefer it to exhibit elastic or plastic deformation? why? consider the functions of a bumper in both a minor "fender-bender" and a major collision.

Apump is used to circulate hot water in a home heating system. water enters the well-insulated pump operating at steady state at a rate of 0.42 gal/min. the inlet pressure and temperature are 14.7 lbf/in.2, and 180°f, respectively; at the exit the pressure is 60 lbf/in.2 the pump requires 1/15 hp of power input. water can be modeled as an incompressible substance with constant density of 60.58 lb/ft3 and constant specific heat of 1 btu/lb or. neglecting kinetic and potential energy effects, determine the temperature change, in °r, as the water flows through the pump.

Burgers vector is generally parallel to the dislocation line. a)-true b)-false
