Define Sustainable development. Is the planet on the path to sustainable development? Give at least two facts to support your opinion.

austral steel company has 2 re rolling plants locations P1 and P2with supply capacities of 100 and 120 tonnes rod (of fixed diameter) per day, respectively. Austral steel has 3 distribution centers at locations DC1, DC2 and DC3. the distribution centers need if possible, 80,120 ,and 60 tonnes of rod each day respectively to meet distribution demands. The shipping socts ($/tonne) is as follows:

From P1 to DC1 = 1

from P1 to DC2 = 2

From P1 to DC3 = 3

From P2 to DC1=4

from P2 to DC 2 = 1

From P2 to DC3 = 5

Develop a formulation for optimal solution to satisfy these constraints

What are the differences between centrifugal compressor and reciprocating compressor?

heat exchanger has water in the outer conduit and ethylene glycol in the inner. It is desired to have a Reynolds number of 1000 in the inner conduit and 15000 in the outer conduit. The inner conduit is 5mm inside diameter and the outer conduit is 12mm inside diameter. Specify the pressure drop per unit length in the each conduit (Pa/m). The inner conduit has a wall thickness of 0.75 mm.

How is life cycle assessment (LCA) used internationally to address the economic consequences of drinking water supply under climate change?

if the truss structure is inverted, explain how this effect on the truss forces and when this geometric arrangement can used in structural schemes ?

10 examples of engineering mechanics in our daily lives?

- A primary sedimentation basin for a municipal waste water treatment plant treats a flow of 3 MGD and removes 70 percent of the total suspended solids..The basin is 60ft in diameter with a depth of 15 ft. the TSS removed (kg)in the basin about ?

A cantilever beam 4m long carries a uniform load of 3.5 kN/m over a portion 1.5m from the free end. E = 200 GPa and I = 30 x 10^6 mm⁴

Using AMM (Area Moment Method):

1. Determine the rotation at the free end.
2. Determine the deflection at the free end.

What kind of rebar would be most cost effective for foundation? Would it be to design for the smallest diameter of rebar and largest amount of distance O.C.?

If water is seeping, the effective stress at any point in a soil mass will be different from the static case. It will decrease or increase depending on the direction of seepage. With help of sketches, describe what will happen to effective stress if the water is seeping downward through a soil layer.

Give two examples of how ductility can be used to analyze a statically indeterminate structure at its strength limit state, as though it were statically determinate.

In a two – story building, an exterior column is to be designed for a service dead load of 1000 KN, maximum live load of 1500 KN, dead load moment of 60 KN m, and live load moment of 90 KN m. If the column dimensions will be restricted to 400 mm x 500 mm, fc’ = 27.6 MPa, and fy = 414 MPa, calculate the required column reinforcement.
