Final answer:
The determination of the resultant internal loadings on a curved member at points B and C requires specific data about the external forces, moments, and the member's geometry. Without these details, it's not possible to provide an answer, hence the choice is (d) not enough information.
Step-by-step explanation:
The student question pertains to the determination of the resultant internal loadings on a curved member at specific points, B and C. This type of question falls under the subject of Engineering, specifically within the scope of statics and strength of materials. The question implies that there is an existing problem setup with a curved structural member being analyzed for internal forces.
In order to calculate the internal loadings at points B and C, information on the external forces, moments, and the geometry of the member is essential. Without that data, it isn't possible to provide a definitive answer to the question. Therefore, the correct choice would be (d) not enough information.
This analysis is necessary for engineers to design and evaluate the structural integrity of objects and materials subject to various types of loads. Understanding internal force distribution is crucial in ensuring safety and functionality in numerous engineering applications.
Therefore the correct option is d. The concept of internal loadings is irrelevant.
