- The purpose of attaching the flywheel is to convert a variable torque into a mean torque on the crankshaft, which it does by storing the surplus energy in some strokes and by supplying the stored energy in other strokes.
- As it is given that T is the torque of the shaft before attaching flywheel and Tmean is the torque of the crankshaft after installing flywheel so we can conclude that (T – Tmean) will be the torque of the flywheel. As it is also given that flywheel is retarding so by using basic equation of Torque = (Moment of Inertia) x (Angular acceleration)
- We can say that if angular acceleration is negative then Torque will also be negative therefore, (T – Tmean) < 0
