Wayback Machine
calls a "three dimensional index". Kahle and Gilliat created the machine hoping to archive the entire Internet and provide "universal access to all knowledge
Answer:
The number is 768
Explanation:
The given parameters of the three digits number are;
The number is a multiple of four, therefore, a factor of the number = 4
The value of the first digit = A prime number larger than 5
The sum of the last two digits > 10
The value of the ones (place value) digit > The tens (place value) digit
Let 'xyz' represent the digits of the three digits number, we have;
x = A prime number digit larger than 5
∴ x = 7
y + z > 10
z > y and z > x
Given that 4 is a factor of the number, we have;
4 is a factor of 'z'
4 is also a factor of yz
Therefore, the digit, z > 7 and z is divisible by 4, therefore, z = 8
y + z = y + 8 > 10
∴ y > 10 - 8
y > 2
The multiples of 4 larger than 728 with the last digit equal to 8 are found using Microsoft Excel and presented as follows;
748, 768, 788
The numbers that have a larger ones place value are; 748 and 768
The sum of the las two digits are therefore, 4 + 8 = 12 and 6 + 8 = 14
The number that has the largest ones place value for the sum of the last two digits is 768
The number is 768
Answer:
A) ν = 0.292
B) ν = 0.381
Explanation:
Poisson's ratio = - (Strain in the direction of the load)/(strain in the direction at right angle to the load)
In axial tension, the direction of the load is in the length's direction and the direction at right angle to the load is the side length
Strain = change in length/original length = (Δy)/y or (Δx)/x or (ΔL/L)
A) Strain in the direction of the load = (2.49946 - 2.5)/2.5 = - 0.000216
Strain in the direction at right angle to the load = (7.20532 - 7.2)/7.2 = 0.0007389
Poisson's ratio = - (-0.000216)/(0.0007389) = 0.292
B) Strain in the direction of the load = (2.09929 - 2.1)/2.1 = - 0.0003381
Strain in the direction at right angle to the load = (5.30470 - 5.3)/5.3 = 0.0008868
Poisson's ratio = - (-0.0003381)/(0.0008868) = 0.381
Answer:
P=- 88.41 KW
Negative sign indicates that power is given to the system.
Explanation:
Given that
P₂=500 KPa
T₂=130°C
V₂=100 m/s
mass flow rate ,m= 0.8 kg/s
Lets take inlet condition for air
T₁=25°C
P₁=100 KPa
V₁=0 m/s
We know that
Heat capacity for air Cp=1.005 KJ/kg.k
We know that for air change in enthalpy only depends only on temperature
Now from first law for open system
W=-110.52 KJ/kg
Shaft power P = m .W
P = -110.52 x 0.8
P=- 88.41 KW
Negative sign indicates that power is given to the system.
