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.
A swimmer, capable of swimming at a speed of 1.2 m/s in still water (i.e., the swimmer can swim with a speed of 1.2 m/s relative to the water), starts to swim directly across a 2.1-km-wide river. How long does it take for the swimmer to cross the r..
When an electron passes through the origin (x = 0, y = 0, z = 0), its velocity has components ofvsubx = 0 m/s, vsuby = +5000 m/s, find the maximum distance the electron gets from the origin in its subsequentmotion
