Pick out the wrong statement about the machinability of metals.

APTITUDE CRACK · Accepted Answer

D decreases with increases in tensile strength &amp; decrease in grain size. The wrong statement about the machinability of metals is: decreases with increases in tensile strength &amp; decrease in grain size. In reality, the machinability of metals generally improves with a decrease in tensile strength and an increase in grain size. So, this statement contradicts the typical relationship between machinability and tensile strength/grain size.
