Consider a frame made of-3 pieces connected together. Assume that no free body diagram cut is within a part. a) How many different free-body diagrams can you draw? b) For each free-body diagram how many independent scalar equations can be extracted from the equilibrium relations? c) In total, from all the free-body diagrams, how many independent scalar equations can be extracted from the various equilibrium conditions.
