Explanation:
Specific cutting energy:
It the ratio of power required to cut the material to metal removal rate of material.If we take the force required to cut the material is F and velocity of cutting tool is V then cutting power will be the product of force and the cutting tool velocity.
Power P = F x V
Lets take the metal removal rate =MRR
Then the specific energy will be

If we consider that metal removal rate and cutting tool velocity is constant then when we increases the cutting force then specific energy will also increase.
Answer:
It's true

I took the quiz a few days ago and got it right!
Hope this helps:)
Take caution, and slow down, it could run out in the middle of the road. Try going around it if possible.
Bending effect!! Whenever the orientation of the diffracting planes changes when the diffracting planes bend, the contrast changes
