Answer:
By definition the ultimate tensile strength is the maximum stress in the stress-strain deformation. The stress at 0.2% strain, the stress at the onset of plastic deformation, the stress at the end of the elastic deformation and the stress at the fracture correspond, by definition, to other points of the stress-strain curve.
Explanation:
...simplify devices, reducing weight and the chance of failure.
Solution:
Given that :
Volume flow is, 
So, 
Therefore, the equation of a single straight vessel is given by
......................(i)
So there are 100 similar parallel pipes of the same cross section. Therefore, the equation for the area is

or 
Now for parallel pipes
...........(ii)
Solving the equations (i) and (ii),




Therefore,

or 
Thus the answer is option A). 10
