What are the answers to these questions? I need help. Thanks.

19. The plate could be subjected to a variety of forces applied at different points. Consider the loads exerted by the pin on the plate, as they would appear in a free body diagram of the plate. The pin is frictionless. Which is the most appropriate partial free body diagram for the loads exerted by the pin on the plate in this situation? The pin loads should be appropriate whatever the other forces on the plate. 20. Part 1 and part 2 are rigidly attached (e.g., welded) to each other. Part 1 could be subjected to a variety of forces applied at different points. Consider the loads exerted by part 2 on part 1 as they would appear in a free body Which is the most appropriate partial free body diagram for the loads exerted by part 2 on part 1? The loads should be appropriate whatever the other forces on diagram of part 1. The pin is frictionless. part 1.

Explanation / Answer

for question 19 , since the support we are considering is pin , it cannot exert any moment reaction, so, only horinontal and vertical forces will be present and their magnitude depends on the external forces applied , so, we cannot fix the angle btw resultant force and horizontal., so, option (a) is correct

for question 20, in the same way we cannot fix the angle and if part 2 applies any moment reaction on part 1 , then by newtons third law, part 1 should apply equal and opposite moment reaction on part 2 , since there are no more external forces on part 2 , and since it is pin jointed, it cannot sustain any moment applied on it , so, applied moment should be counter acted by the horizontal force offered by part 1 on part 2 . so, option (a) is correct
