Question: Suppose in Problem that the specimen is steel. Based on the Brinell hardness number determined in that problem, estimate the tensile strength of the steel.

Problem: In a Brinell hardness test, a 1500-kg load is pressed into a specimen using a 10-mm-diameter hardened steel ball. The resulting indentation has a diameter = 3.2 mm. Determine the Brinell hardness number for the metal.
