Crank and Connecting Rod Objective To obtain the displacement diagram for the piston of a crank and connecting rod assembly Theory The slider crank chain is one of the two basic mechanisms which from the basic for many more complicated motions. (The others are the four Bar Chain‚ Scoth Yoke or Chebyshev linkage of which over 800 forms are known). It transforms linear motion to circular motion or vice versa. A crank is an arm attached at right angles to a rotating shaft by which reciprocating
