Answer:
The material will not fail
Explanation:
A rod subjected under cyclic stress will fail if the cyclic stress it is subjected to is a constant maximum value that is above the fatigue limit of the rod. but in this problem the Rod is subjected to a cyclic stress that ranges from 200 MPa(maximum stress) and 20 MPa ( minimum stress). this simply means that at all times the Rod will not experience maximum stress of 200 MPa and its Fatigue limit is also set at ~100 MPa
attached is the diagram showing the cyclic stress the rod is subjected to
Answer:
evaluative criteria.
Explanation:
Evaluative criteria is a term in marketing that Is used when a customer decides to go for a different kind of product that is different from the one they originally had in mind because of certain attributes. These attributes could be objective in nature such as power and fuel economy or it could subjective when things like prestige and convenience are being looked at.
An architectural engineer is a person who is responsible for studying and evaluating construction blueprints and designs. This is to determine if the design is feasible and if it is feasible to construct. Building styles and aesthetics should not be prioritized over the structural integrity and safety of a proposed building. Plan, construct, and prototype buildings, and be able to identify, analyze, and resolve issues with them as they arise.
