Answer:
(a)- cutting tools
Explanation:
High speed steel is the cutting tool material .It is widely used in the production process.it also represent as HSS.High speed steel is made from heat treatment process of steel .
The high speed steel have following compositions
1.Tungsten - 18 %
2.Chromium - 4%
3. Vanadium- 1 %
4.Carbon - 0.7 %
5.Iron - 76.3 %
So the option a is correct.
(a)- cutting tools
The designers suggest that speech recognition allows for spoken interaction or conversation and spoken prompts or commands.
Explanation:
The speech recognition is used when the user has physical impairments and hands are busy, eyes are occupied and the user cannot read.
We can save time with the usage of speech recognition system. The users are knowledgeable based on the actions available.
The problems faced in speech recognition system are in the noisy environment it has bad microphones and the commands should be learned and remembered.
The other obstacle is error correction is time consuming. the speech production has slow space to speech output provides privacy in public spaces. The disadvantage is it contains large amount of information.
Answer:
0.65 m/min
Explanation:
The volume of material to be removed is
80*8*10 = 650 cm^3
The tool has a diameter of 4 mm and a maximum axial cutting capacity of 50 mm, so its cross section normal to advance is
0.4*5 = 2 cm^2
If the groove have to be made in T = 5 minutes the advance speed would be
V/(S * T)
650/(2 * 5) = 65 cm/min = 0.65 m/min
Answer:
ΔP=19.76 KPa
Explanation:
Given that
atmospheric pressure = 100 kPa.
So absolute pressure = Atmospheric pressure + gauge pressure
(absolute)
(absolute)
Here volume of air is constant .We know that for constant volume pressure
here
(absolute)
So rise in pressure
ΔP=329.76-310 KPa
ΔP=19.76 KPa
Δm=0.090615 - 0.090614 kg
