Final answer:
The student's question involves engineering mechanics but cannot be accurately answered due to insufficient information and lack of context. To solve for normal force, shear force, and moment, one needs a complete set of details, which are not provided.
Step-by-step explanation:
The student is asking about the analysis of forces on a structure, which is a common problem in the field of engineering mechanics, specifically in statics. However, the given information is not sufficient to provide an accurate solution as there are undefined variables and missing context. Without a diagram or additional details, we cannot determine the normal force, shear force, and moment at points · and ¸. When dealing with such problems, it's crucial to have all the geometrical and loading details to apply equilibrium equations and find the requested forces and moments. For an accurate analysis, one must consider all the forces acting on the structure including the coefficient of static friction, the normal force, and any applied forces or reactions at supports or connections.
