Consider the following statements: 1. The working stress design is based on explicit consideration of the various conditions under which the structure may cease to fulfill its intended function. 2. In the case of working stress design, the structure will directly take into consideration the various relevant modes of failure. 3. In the working stress method, regulatory bodies or classification societies usually specify the value of the allowable stress as some fraction of the mechanical properties of materials Which of the above statements is/are correct?

Correct Answer 3 only
Explanation:
- Limit state design is based on the explicit consideration of the various conditions under which the structure may cease to fulfill its intended function
- The structure can not directly take into consideration the relevant modes of failure. For example, an increase in stress near the openings of a steel plate can not be accounted for directly in the working stress method.
- In the working stress method, regulatory bodies or classification societies usually specify the value of the allowable stress as some fraction of the mechanical properties of materials that are usually based on similar past experiences.
