Answer:
L = 75.25 mm
Explanation:
First we need to find the lateral strain:
Lateral Strain = Change in Diameter/Original Diameter
Lateral Strain = (20.025 mm - 20 mm)/20 mm
Lateral Strain = 1.25 x 10⁻³
Now, we will find the Poisson's Ratio:
Poisson's Ratio = (E/2G) - 1
where,
E = Elastic Modulus = 105 GPa
G = Shear Modulus = 39.7 GPa
Therefore,
Poisson's Ratio = [(105 GPa)/(2)(39.7 GPa)] - 1
Poisson's Ratio = 0.322
Now, we find longitudinal strain by following formula:
Poisson's Ratio = - Lateral Strain/Longitudinal Strain
Longitudinal Strain = - Lateral Strain/Poisson's Ratio
Longitudinal Strain = - (1.25 x 10⁻³)/0.322
Longitudinal Strain = - 3.87 x 10⁻³
Now, we can fin the original length:
Longitudinal Strain = Change in Length/L
where,
L = Original Length = ?
Therefore,
- 3.87 x 10⁻³ = (74.96 mm - L)/L
(- 3.87 x 10⁻³)(L) + L = 74.96 mm
0.99612 L = 74.96 mm
L = 74.96 mm/0.99612
L = 75.25 mm
Answer:
x3=0.100167
Explanation:
Let's find the answer.
Because we are going to find the solution for sin(Ф)=0.1 then:
f(x)=sin(Ф)-0.1 and:
f'(x)=cos(Ф)
Because 0<Ф<π/2 let's start with an initial guess of 0.001 (x0), so:
x1=x0-f(x0)/f'(0)
x1=0.001-(sin(0.001)-0.1)/cos(0.001)
x1= 0.100000
x2=0.100000-(sin(0.100000)-0.1)/cos(0.100000)
x2=0.100167
x3=0.100167
Answer:
Va / Vb = 0.5934
Explanation:
First step is to determine total head losses at each pipe
at Pipe A
For 1/4 open gate valve head loss = 17 *Va^2 / 2g
elbow loss = 0.75 Va^2 / 2g
at Pipe B
For 1/3 closed ball valve head loss = 5.5 *Vb^2 / 2g
elbow loss = 0.75 * Vb^2 / 2g
Given that both pipes are parallel
17 *Va^2/2g + 0.75*Va^2 / 2g = 5.5 *Vb^2 / 2g + 0.75 * Vb^2 / 2g
∴ Va / Vb = 0.5934

Explanation:
The program analyses a set of male and female names and displays, the combined set of names, specific names and neutral names. The program written in python 3 goes thus :
male_names = {'John', 'Bailey', 'Charlie', 'Chuck', 'Michael', 'Samuel', 'Jayden', 'Aiden', 'Henry', 'Lucas'}
#setofmalenames
female_names = {'Elizabeth', 'Meghan', 'Kim', 'khloe','Bailey', 'Jayden' , 'Aiden', 'Britney', 'Veronica', 'Maria'}
#setoffemalenames
neutral_names = male_names.intersection(female_names)
#names common to both males and females
all_names = male_names.union(female_names)
#set of all baby names ; both male and female
specific_names = male_names.symmetric_difference(female_names)
#name in one set and not in the other
print(all_names)
print(' ')
#leavesaspaceinbetweenthelines
print(specific_names)
print(' ')
print(neutral_names)
