A Brinell hardness tester is used to determine the hardness of
1/2" thick steel plate. The specifications for the steel require
that 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 the
steel.
B. If a hardness test reveals that the Brinell hardness of the
steel plate is 260 BHN what is the diameter of the indention in the...

Problem 3: Metal Hardness Testing
The manufacturer of hardness testing equipment uses steel-ball
indenters to indent metal that is being tested. However, the
manufacturer thinks there might be a difference in hardness reading
when using a diamond indenter. The metal specimens to be tested are
large enough so that two indentations can be made. Therefore, the
manufacturer wants to use both indenters on each specimen and
compare the readings. The order of the indentations will be random.
This particular design...

The manufacturer of hardness testing equipment uses steel-ball
indenters to penetrate metal that is being tested. However, the
manufacturer thinks it would be better to use a diamond indenter so
that all types of metal can be tested. Because of differences
between the two types of indenters, it is suspected that the two
methods will produce different hardness readings. The metal
specimens to be tested are large enough so that two indentions can
be made. Therefore, the manufacturer uses both...
