Engineering strain of a mild steel sample is recorded as $$0.100\% .$$ The true strain is

Match the following products with preferred manufacturing process:

In a rolling process, the maximum possible draft, defined as the difference between the initial and the final thickness of the metal sheet, mainly depends on which pair of the following parameters?
$$P:$$ Strain
$$Q:$$ Strength of the work material
$$R:$$ Roll diameter
$$S:$$ Roll velocity
$$T:$$ Coefficient of friction between roll and work.

The relationship between true strain $$\left( {{\varepsilon _T}} \right)$$ and engineering strain $$\left( {{\varepsilon _E}} \right)$$ in a uniaxial tension test is given as
