Answer:
The hardness test is preferred to tensile test because it is simple, easy, and relatively nondestructive.
Tensile testing is a destructive test process that checks tensile strength, yield strength, and ductility of the metallic material.
Explanation:
Hardness test is a test carried out to check the resistance of a material to withstand permanent deformation such as indentation, wear, abrasion, scratch. It evaluates a material’s properties, such as strength, ductility, permanent deformation and wears resistance, and so helps you determine whether a material or material treatment is suitable for the purpose you require. This test is carried out by penetration of the material through another harder material.
Tensile testing is one of the most common mechanical testing techniques used to test the strength of material and also how much it can be stretched before it breaks. It is a destructive test process that provides information about the tensile strength, yield strength, and ductility of the metallic material.
Answer:
In planning a program, the following features are important.
- Knowing what you want the program to do.
- Knowing how to find the result needed.
- Knowing what the user needs the program to accomplish
- Knowing what information is needed to find the result
You start out by planning on what you want to create. Then you think of what programming language to use. The features to be included and then the task you want this program to accomplish
Answer: fake water all across the road
Explanation:
The program is an illustration of a sequential program.
Sequential programs are programs that do not require conditions
<h3>The program</h3>
The program written in Python is as follows:
radius = float(input("Radius: "))
diameter = 2 * radius
circumference = diameter * 3.14
surfaceArea = 4 * 3.14 * radius**2
volume = (4.0/3) * 3.14 * radius**3
print(diameter)
print(circumference)
print(surfaceArea)
print(volume)
