Answer:
r=0.31
Ф=18.03°
Explanation:
Given that
Diameter of bar before cutting = 75 mm
Diameter of bar after cutting = 73 mm
Mean diameter of bar d= (75+73)/2=74 mm
Mean length of uncut chip = πd
Mean length of uncut chip = π x 74 =232.45 mm
So cutting ratio r


r=0.31
So the cutting ratio is 0.31.
As we know that shear angle given as

Now by putting the values

\
Ф=18.03°
So the shear angle is 18.03°.
Answer:
Output voltage equation is 
Explanation:
Given:
dc gain
dB
Input signal 
Now convert gain,

DC gain at frequency
is given by,



At zero frequency above equation is written as,


Now we write output voltage as input voltage,

Therefore, output voltage equation is 
Answer:
-25.63°C.
Explanation:
We know that throttling is a constant enthalpy process

From steal table
We know that if we know only one property in side the dome then we will find the other property by using steam property table.
Temperature at saturation pressure 1 bar is 99.63°C and Temperature at saturation pressure 0.35 bar is about 74°C .
So from above we can say that change in temperature is -25.63°C.
But there is no any option for that .
