DESIGN OF SHAFT FOR SPUR GEAR Wt

Normal load Wn = ----------- cosØ

Weight of the gear WG = 0.00118*T*b*m*m

Resultant load wR = wn2 + wg

ENERGY STORED IN FLY WHEEL Kinetic energy of fly wheel, E = ½ I 2

Since I = m k2 , E = ½ I k2 2

As speed of flywheel changes from <ox to a>2 the maximum fluctuation of energy. ΔE = maximum KE - minimum KE = I 2 Cs

= m k2 2 Cs

= 2ECS

Where I = moment of inertia of fly wheel about the axis M = mass of fly wheel in Kg K = radius of gyration of fly wheel in meters = mean angular speed in rad/sec. Cs = co-efficient of fluctuation of speed
