Answer:
555.936 kg
Explanation:
h = Length of pipe = 4 m
r = Inside radius =130 mm
R = Outside radius = 150mm
Volume of the cylinder
v = πR²h - πr²h
⇒v = πh(R²-r²)
⇒v = π4(0.15²-0.13²)
⇒v = 0.0704 m³
Density of steel varies between 7,750 and 8,050 kg/m³
So, let us take the average of the two values so we get density of steel as 7900 kg/m³ as the exact density is not given
Density

So, approximate mass of the steel pipe is 555.936 kg
Answer:
answer is given below
Explanation:
Declaration for garnet
- void garnet(char,int (*f)(int));
- void - garnet return nothing
garnet accepts two parameters
- 'Char'
- function
Function as a parameter
and here
first int refers return type of function
- (*f) function as pointer variable
second int
- arguments that accept by inner function- function as a parameter
so here Garnet is a function that accepts two parameters. One parameter that contains the character and another parameter that takes an argument (here I am taking an integer) and returns an integer. Function The function returns nothing. Zero is mentioned here.
Answer: ε₁+ε₂+ε₃ = 0
Explanation: Considering the initial and final volume to be constant which gives rise to the relation:-
l₀l₀l₀=l₁l₂l₃

taking natural log on both sides

Considering the logarithmic Laws of division and multiplication :
ln(AB) = ln(A)+ln(B)
ln(A/B) = ln(A)-ln(B)

Use the image attached to see the definition of true strain defined as
ln(l1/1o)= ε₁
which then proves that ε₁+ε₂+ε₃ = 0
All I need is one more.
