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 diagram of part 1. The pin is
frictionless.
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 part
1.
