Which of the following is not one of techniques for financial appraisals?


Which of the following is not one of techniques for financial appraisals?

  1. The market approach that uses prices and other relevant information generated by market transactions involving identical or comparable assets, liabilities, or a group of assets and liabilities. 

  2. The cost approach which reflects the amount that would be required currently to replace the service capacity of an asset. 

  3. The income approach that converts future amounts (such as cash flows or income and expenses) to a single current (discounted) amount. 

  4. The appraisal approach that uses the result of financial appraisal done by experts.

  5. None of the above.

Pavement performance is an important factor in pavement design because it provides a framework upon which a judgement on the road is either success or failure, which is associated with the ability of the pavement to carry out the design loading. Based on these statements, briefly discuss a distinction between the two different types of failures.

The study of the mechanics of solids is a central object in the formation of various engineering modalities. And it is not for nothing that it is mandatory discipline in almost all engineering. Almost every concrete human achievement (not just intellectual or virtual), be it a building, a machine, equipment or even a (plastic) work of art, needs a structural support, something that can perform its function mechanically .... (José Roberto de F Arruda). 
Given the great importance of solid mechanics in Engineering, cite and comment on 3 examples of the application of Solid Mechanics in our daily lives, and their importance in solving engineering problems.
