Task 1 - Detailed justifications are included in Tasks 2, 3 & 4 whereby the component listed matches with the description of the process.
Also the justification for why these items have been chosen is that from the extensive research that I have done I have found evidence that states that these components are used it the particular processes chosen.

Characteristics of Forming Sheet Material Table:
ElongationDetermines the capability of the sheet metal to stretch without necking and failure.
Yield point elongationObserved with mild steel sheets, also called Lueder's bands and stretcher strains. Causes flame like depressions on the sheet surfaces but can be eliminated by temper rolling, but the sheet must be formed within a certain time period after rolling.
AnisotropyDetermines thinning behaviour of sheet material during stretching - important...
