Answer:
"Tempering Process" seems to be the appropriate choice.
Explanation:
- Tempering seems to be a method of heat preparation which is mostly used in completely hard materials to increase consistency, strength, durability, and also some decreasing brittleness.
- The tempering method is used to examine good functionality as well as flexural by reducing stiffness again after the substance has indeed been quenched towards its toughest state.
Answer:Discrete system are those system which change the state at the discrete point of time and continuous system are those which have state change at continuous period of time.
Explanation:
- The major difference between discrete and continuous system is that, discrete system has state change over a discontinuous time period whereas the change of state in continuous system is over a continuous time period .
- Variations can be found in the discrete system signal but in continuous system variation cannot be found input and output signal.
- Example:-
Discrete system:-employees reporting at office at different time like
9:10am, 9:15am etc
<u> Continuous system</u>:-the water flow over a dam in particular quantity
Answer:
Temperature to which the shaft must be cooled, 
Explanation:
Diameter of the shaft at room temperature, d₁ = 40 mm
Room temperature, θ₁ = 21°C
Coefficient of thermal expansion, 
The shaft is reduced in size by 0.20 mm:
Δd = - 0.20 mm
The temperature to which the shaft must be cooled, θ₂ = ?
The coefficient of thermal expansion is given by the equation:
