A metal specimen was subjected to a Vickers hardness test. The indentation on the surface of the specimen had a measured diagonal, d, of 0.24mm and the Vickers hardness number was calculated at a value of 482.91kgf/mm². Determine the applied force, F, that was used to test the specimen. Also, determine the Tensile Strength of the metal, assuming it is hard.

ANSWER Q4 PART B
Q1/A structural part is 1-meter-long and subjected to a 50 KN load in which this part must be deformed elastically without experiencing any permanent deformation. If you know that part is made of steel, brass, aluminum, and Titanium alloys and the yield strengths and densities of these alloys are: 860 MPa, 7.9 g/cm³; 415 MPa, 8.5g/cm³; 310 MPa, 2.7 g/cm³; and 550 MPa, 4.5 g/cm³ respectively. Based on these criteria, rank the alloys from the heaviest to the lightest in weight.
