Question

The following data is given for a rimmed flywheel made of grey cast ron.

Mean radius of the rim = 1 m, Thickness of the rim = 115 mm

Width of the rim = 220 mm, Number of spokes = 4

Cross-sectional area of each spoke = 6500 mm. Speed of rotation = 770 rpm

Mass density of flywheel = 7250 kg m
