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.

Acompressor receives the shaft work to decrease the pressure of the fluid. a)- true b)- false

Consider a large isothermal enclosure that is maintained at a uniform temperature of 2000 k. calculate the emissive power of the radiation that emerges from a small aperture on the enclosure surface. what is the wavelength ? , below which 10% of the emission is concentrated? what is the wavelength ? 2 above which 10% of the emission is concentrated? determine the wavelength at which maximum spectral emissive power occurs. what is the irradiation incident on a small object placed inside the enclosure?

Draw the engineering stress-strain curve for (a) bcc; (b) fcc metals and mark important points.
