Question $6(9\mathrm{.}9$ points$)$

You have been provided with the tabulated data of the tensile test of one of the

following metals:

Ultra$-$high$-$strength structural steel: $900-1500$MPa

Titanium: $820-880$MPa

Stainless steel: $550-820$MPa

Aluminum: $200-300$MPa

Structural steel: $350-400$MPa

Cast iron: $130-200$MPa

Identify the metal by computing" its yield strength.

$"$To compute means to calculate numerically to a minimum of four decimal places.

$x^{**}=($The sum of the last three digits of your student mumber$).$ For example, if your

student number is $xxx1234,x^{\text{'}}$ is equal to $2+3+4=9.$
