Negative Positive
Title: Infuriating
Review: A screw has 8 threads per inch and a vise must travel 2 inches along it. How many revolutions must the handle make? 16, right? The book says 18, with no explanation of the mysterious missing threads. Do you have to spin a couple of times to get going?In short, the explanations stink (the editors routinely use oddball approaches in their math and skip whole series of steps) and there is not enough background material or pointers to references.The entire mechanical comprehension section is lifted wholesale out of two freely-available Navy manuals and the test questions are just the examples that the Navy used.There is no online companion to this - not even an errata so the authors could point out some of their mistakes.I take this exam next week and I'm scared.
