Design of Centre Crankshaft

A crankshaft is subjected to bending and torsional moments due to the following three forces:
(i) Force exerted by the connecting rod on the crank pin.
(ii) Weight of flywheel acting downward in the vertical direction.
(iii) Resultant belt tensions acting in the horizontal direction.
In the design of the center crankshaft, two cases of the crank, positions are considered. They are as follows:
Case I: The crank is at the top dead center position and subjected to maximum bending moment and no torsional moment.
Case II: The crank is at an angle with the line of dead center positions and subjected to maximum torsional moment.
