The turning-moment diagram for an engine, which has been drawn to scales of 1 mm to 50 Nm and I mm to 1° of rotation of crankshaft, shows that the greatest amount of energy which has to be stored by the flywheel is represented by an area of 2250 mm 2. The flywheel is to run at a mean speed of 240 rpm with a total speed variation of 2 per cent. If the mass of the flywheel is to be 450 kg, determine suitable dimensions for the rim, Cast iron has a density of 7.2 Mg/m3.

Basic Terminology in Mechanics

The area of science and mathematics concerned the motion of the objects, the relation between the force matter, and motion if specified. Forces exerted over the objects result in displacements or changes in the position of an object concerning its environment. This branch of physics keeps its roots in Ancient Greece in the form of the scripts of Aristotle and Archimedes.

Question

The turning-moment diagram for an engine, which has been drawn to scales of 1 mm to 50 N m and I mm to 1° of
rotation of crankshaft, shows that the greatest amount of energy which has to be stored by the flywheel is represented by
an area of 2250 mm 2. The flywheel is to run at a mean speed of 240 rpm with a total speed variation of 2 per cent. If the
mass of the flywheel is to be 450 kg, determine suitable dimensions for the rim, Cast iron has a density of 7.2 Mg/m3.
