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:
Trace topology is also referred to as tree bus topology.
Explanation:
Answer:
The answer to the given question is the option "B".
Explanation:
In this question, the answer is false because the UDP is not reliable for the data flow control. In the transport layer protocol it two protocols to serving the transportation layer that is TCP and UDP.
- In the network layer, IP protocol sends a datagram to the destination host from a source host. When a host sends a message to another host, the origin process sends a request to a process of destination.
- The Transport layer protocol is a part of the UDP and is not reliable.
That's why the answer to this question is "false".
