Turning Moment Diagrams and Flywheel topics include: Energy fluctuation, flywheel and its energy storage, coefficient of speed and energy fluctuation, turning moment diagram for single and multi cylinder engine and also four stroke cycle combustion engine. A turning moment diagram, also known as a crank effort diagram, is a graphical representation of the relationship between the turning moment and the crank angle at various crank positions. It can be used to design a flywheel for an engine to minimize crank speed variance during each cycle.  A flywheel is a mechanical device that stores... Show more

1. An Internal combustion engine has a connecting rod of mass 2 kg and the distance between the centre of crank and centre of gudgeon pin is 25 cm. The Center of Gravity lies at a point 10 cm from the gudgeon pin along the line of centres. The radius of gyration of this system about an axis through the Center of Gravity perpendicular to the plane of rotation is 11 cm. Find the mass located at gudgeon pin in Kg.
