Option 2 : 2 × depth of cut

Explanation:

Turning:

  • Turning is a process in which the workpiece is rotated and a cutting tool removes a layer of material as the tool moves to the left.
  • In the turning process, the cutting tool is set at a certain depth of cut (mm) and travels to the left with a certain velocity as the workpiece rotates.
  • The feed, or feed rate, is the distance the tool travels horizontally per unit revolution of the workpiece (mm/rev). This movement of the tool produces a chip, which moves up the face of the tool.
  • Change in diameter is equivalent to 2 × (depth of cut) of the workpiece in turning.
  • The radius changes according to the depth of the cut that is provided as it removes the material from the complete periphery of the job.

All actions to address climate change ultimately involve costs. Funding is vital in order for countries like India to design and implement adaptation and mitigation plans and projects. The problem is more severe for developing countries like India, which would be one of the hardest hit by climate change, given its need to finance development. Most countries do indeed treat climate change as real threat and are striving to address it in a more comprehensive and integrated manner with the limited resources at their disposal. With reference to the above passage, the following assumptions have been made: 1. Climate change is not a challenge for developed countries. 2. Climate change is a complex policy issue and also a development issue for many countries. 3. Ways and means of finance must be found to enable developing countries to enhance their adaptive capacity. Which of the above assumptions is/are valid?
