Explanation:
There are two rake angle types :
Positive rake
This is the case that occurs when looking from the inner side the face of the cutting tool slopes away from the cutting edge.
Negative rake
This is the case that occurs when the face of the cutting tool slopes away from the cutting edge at the outer side.
Increasing the positive rake angle means that the cutting tool will get sharper thus making the tool weaker. So, brittle material will form discontinuous chips and ductile material will form continuous chip. The tool life may also be reduced.
Increasing the negative rake angle means that the cutting tool will get blunt thus making the tool stronger. So, brittle material will form continuous chips. Results in higher temperature of the tool. Surface finish might increase.
Answer:
ABS warning light – it is turned on every time there's something wrong with the Anti-lock Brake System. Note that the ABS symbol is activated once the drive starts the engine but it's automatically turned off after a few seconds.
Explanation:
Answer:
(b) BC → A
Explanation:
For given instance of S, certain dependencies (that is to say, A → B and B → C) can be said that they are not violated by this instance of S.
It can be said that an FD holds with respect to a relationship is to make a claim about all appropriate instances of S.
BC → A does not hold over S. To confirm, let's look at the tuples (1, 2, 3) and (4, 2, 3).
Hence, the answer is (b) BC → A.
