The correct answer is A
Faraday and Weber
:)
Answer: True
Explanation:
Engineering stress is the applied load divided by the original cross-sectional area of a material. It is also known as nominal stress. It can also be defined as the force per unit area of a material. Engineering Stress is usually in large numbers.
While Engineering strain is the amount that a material deforms per unit length in a tensile test. It can also be defined as extension per unit length. It has no unit as it is a ratio of lengths. Engineering Strain is in small numbers.
Answer:
The time taken will be "1 hour 51 min". The further explanation is given below.
Explanation:
The given values are:
Number of required layers:
= 
= 
Diameter (d):
= 1.25 mm
Velocity (v):
= 40 mm/s
Now,
The area of one layer will be:
= 
= 
The area covered every \second will be:
= 
= 
= 
The time required to deposit one layer will be:
= 
= 
The time required for one layer will be:
= 
∴ Total times required for one layer will be:
= 
= 
So,
Number of layers = 152
Therefore,
Total time will be:
= 
= 
=
