Mechanical Engineering

A Brinell hardness tester is used to determine the hardness of1/2\" thick steel plate. The specifications for the steel requirethat the steel have a tensile strength between 125 ksi and 150 ksi.A 3000 kg load is used for the test.

A. Calculate the minimum and maximum Brinell hardness of thesteel.

B. If a hardness test reveals that the Brinell hardness of thesteel plate is 260 BHN what is the diameter of the indention in thesurface of the plate from the Brinell hardness test?
