1.A steel railroad track (Es=200 GPA, as=11.7x10-6/oC) was laid out at a temperature of 6/oC. Determine the normal stress in the rails when the temperature reaches 48oC assuming that the rails

(a) are welded to form a continuous track

(b) are 10m long with 3 mm gaps between them.

2.A tidal channel, which may be assumed to be rectangular, is 40 m wide and conveys a discharge of 60 m3/s at a depth of 1.52 m. A tidal bore is seen to propagate upstream with a wave speed of 5 m/s. Determine the depth of flow and the discharge immediately after the bore has passed.

Tidal Bore

Vw = c1 - V1 or Vw = c2 + V2

3.The environmental performance of a product depends strongly on the way it used. The use of a ceramic coffee mug in preference to a disposal polystyrene coffee cup has been the subject of considerable discussion. Discuss the advantages and disadvantages of the usage of ceramic coffee mugs.
