hung
hanged

"I hung the picture yesterday."
"The man was tried and hanged." <-- *NOT* hung.

When you say "The man was hung yesterday" you're not talking about ropes.

sit
set

If it is a living animal/ being, it 'sits'.
I watched the large Harley rider sit on the bench.

If it is not a living being it is SET.
I set the vase on the table.
