good question i like to give about 20. i think people just are cheapskates for most of their time on this planet. didnt need the 50 though but thanks.
 
        
                    
             
        
        
        
Answer:
Check the explanation
Explanation:
The loop invariant has to satisfy some amount of requirements to be of good use. Another complex factor as to why a loop is the question of loop termination. A loop that doesn’t terminate can’t invariably be correct, and in fact the computation in whatever form amounts to nothing. The total axiomatic description of a while construct will have to involve all of the following to be true, in which I is the loop invariant:
P => I
{I and B} S {I}
(I and (not B)) => Q
Then the loop terminates
 
        
             
        
        
        
Answer:
Diesel cycle:
     All diesel engine works on diesel cycle.It have four processes .These four processes are as follows
1-2.Reversible adiabatic compression
2-3.Heat addition at constant pressure
3-4.Reversible adiabatic expansion
4-1.Heat addition at constant volume
When air inters in the piston cylinder after that it compresses and gets heated due to compression after that heat addition take place at constant pressure after that power is produces when piston moves to bottom dead center.
From the diagram of P-v And T-s we can understand so easily.
 
 
        
             
        
        
        
Answer:
Part a: The yield moment is 400 k.in.
Part b: The strain is 
Part c: The plastic moment is 600 ksi.
Explanation:
Part a: 
As per bending equation

Here 
- M is the moment which is to be calculated
- I is the moment of inertia given as 
                          
Here 
- b is the breath given as 0.75"
- d is the depth which is given as 8"
                      
                      

The yield moment is 400 k.in.
Part b: 
The strain is given as 

The stress at the station 2" down from the top is estimated by ratio of triangles as 
                         
Now the steel has the elastic modulus of E=29000 ksi

So the strain is 
Part c: 
For a rectangular shape the shape factor is given as 1.5.
Now the plastic moment is given as 

The plastic moment is 600 ksi.
