Answer #1

Engineers can use hardness testing to verify the composition or heat-treatment history of materials. It enables engineers to evaluate materials properties such as ductility, strength and wear resistance. Hardness is the property of a material that enables it to resist plastic deformations penetration indentation and scratching It is recognised by this test that the material is suitable for the purpose. There are various hardness test such as Rockwell, Brinell and Vickers. The most common type of hardness test is Rockwell. It is fast and reliable to determine the strength of metal

An engineer measured the Brinell hardness of 25 pieces of ductile iron that were subcritically annealed. The resulting data were: 170 167 174 179 179 187 179 183 179 156 163 156 187 156 167 156 174 170 183 179 174 179 170 159 187 The engineer hypothesized that the mean Brinell hardness of all such ductile iron pieces is greater than 165. The engineer analyzed his data and calculated the following: The average Brinell hardness of the n =...

The Journal of Professional Issues in Engineering Education and Practice (Apr. 2005) reported on the results of a 2005 survey of courses offered at undergraduate engineering programs. Of the 90 engineering programs that participated in the 2005 survey, 68 covered fluid mechanics. In a survey taken 20 years earlier (Engineering Education, Apr. 1986), 66 of the 100 undergraduate engineering programs covered fluid mechanics. Conduct a test to determine whether the fraction of undergraduate engineering programs covering fluid mechanics increased from...
