Final answer:
Schedule is not a common dimension in a feasibility study. Feasibility studies usually include technical, operational, and economic dimensions. Engineers should also consider scientific, ethical, economic, and legal aspects in large-scale problems.
Step-by-step explanation:
The dimension that is not common in a feasibility study from the options provided is (c) Schedule. Feasibility studies typically focus on several key areas to assess the viability of a project. These areas commonly include technical feasibility, which examines if the technology needed for the project is available and capable; operational feasibility, which looks at how well the project plan meets the requirements and if the organization is able to carry out the plan; and economic feasibility, also known as financial feasibility, which analyzes whether the project is financially viable. While schedule can be a factor in project planning, it is not usually classified as a standalone dimension of feasibility studies.
When looking at large-scale problems, engineers should focus on aspects that are critical to both the success and integrity of the project. These include (1) scientific aspects, ensuring the project is grounded in solid scientific principles; (2) ethical aspects, ensuring the project adheres to ethical standards; (3) economic aspects, ensuring the project is financially sound; and (4) legal aspects, ensuring the project complies with all applicable laws and regulations.
