LATHE CUTTING TOOLS - Practice Mode

1) Which property avoid the breakage of cutting edge of tools?
Correct Answer: Toughness
Explanation:

The boiling point of water on the Fahrenheit scale is 212°F (100°C). This is the temperature at which water changes from a liquid to a gas (vapor) at standard atmospheric pressure (1 atm). 

At this temperature, the vapor pressure of water is equal to the surrounding atmospheric pressure, and as a result, the liquid water will begin to boil and turn into steam.

2) Which is the example of ferrous tool material?
Correct Answer: H.S.S
3) What is the property of tool material to resist sudden shock load?
Correct Answer: Toughness
Explanation:

To convert temperature in degrees Celsius to Fahrenheit, you can use the following conversion formula: F = (9/5) * C + 32

Where F is the temperature in Fahrenheit and C is the temperature in Celsius.

Given that you need to convert 45 degree C to degree F F = (9/5) * 45 + 32 F = 113 Fahrenheit (°F)

So, 45 degrees Celsius is equivalent to 113 degrees Fahrenheit (°F).

4) Which property of the cutting tool the amount of hardness possessed by a material at normal temperature?
Correct Answer: Cold hardness
Explanation:

There is one point on the Fahrenheit and Celsius scales where the temperatures in degrees are equal. This is -40 °C and -40 °F.

5) Which among the tool material belongs to non metallic tool material?
Correct Answer: Ceramics
Explanation:

The Kelvin (K) temperature scale is a scale of measurement for temperature that is based on the absolute zero point, which is defined as 0 K. The difference between the Kelvin and Celsius scales is that the Kelvin scale starts at absolute zero, while the Celsius scale starts at the freezing point of water.

To convert a temperature measured in degrees Celsius (°C) to Kelvin (K), you can use the following formula:

Temperature in Kelvin = Temperature in Celsius + 273.15

In your case, you want to convert -273°C to Kelvin, to do that you need to add 273.15 to -273,

-273 + 273.15 = 0

So -273 degrees Celsius is equivalent to 0 Kelvin.
