Explanation:
Given
Using Newton's law of cooling
=
=
7=
Taking log both side
t=112.376sec
Answer:
Explanation:
Pie charts generally should have no more than eight segments.
Pseudocodes are used as a prototype of an actual program.
The error in the pseudocode is that, the while loop in the pseudocode will run endlessly.
From the pseudocode, the first line is:
<em>Declare Boolean finished = false</em>
The while loop is created to keep running as long as <em>finished = false.</em>
So, for the while loop to end, the finished variable must be updated to true.
This action is not implemented in the pseudocode.
Hence, the error in the pseudocode is that, the while loop is an endless loop

Answer:
All 3 principal stress
1. 56.301mpa
2. 28.07mpa
3. 0mpa
Maximum shear stress = 14.116mpa
Explanation:
di = 75 = 0.075
wall thickness = 0.1 = 0.0001
internal pressure pi = 150 kpa = 150 x 10³
torque t = 100 Nm
finding all values
∂1 = 150x10³x0.075/2x0,0001
= 0.5625 = 56.25mpa
∂2 = 150x10³x75/4x0.1
= 28.12mpa
T = 16x100/(πx75x10³)²
∂1,2 = 1/2[(56.25+28.12) ± √(56.25-28.12)² + 4(1.207)²]
= 1/2[84.37±√791.2969+5.827396]
= 1/2[84.37±28.33]
∂1 = 1/2[84.37+28.33]
= 56.301mpa
∂2 = 1/2[84.37-28.33]
= 28.07mpa
This is a 2 d diagram donut is analyzed in 2 direction.
So ∂3 = 0mpa
∂max = 56.301-28.07/2
= 14.116mpa
