problem1) What is the purpose of the flop jig? List two major disadvatages associated with the use of leaf jigs?
problem2) Draw signal-flow graph equivalence of the block diagram below and obtain closed-loop transfer function between R(s) and C(s).
problem3) In the figure below is shown a 1-in. solid round shaft supported by self-aligning bearings at A and B. Attached to shaft are two chain sprockets whichare loaded as shown. Treat this as static loading problem, ignoring fatigue and stress connection. Identify specific shaft location subjected to the most severe state of stress, and make a Mohr circle representation of this stress state.
