Question 5
A flywheel is now connected with an Internal Combustion Engine (ICE), through a crank shaft. The
energy diagram of the flywheel is shown in Figure 4. The flywheel has a mass of 2.5 kg, angular
velocity w, is 5000T-rad/min, radius of 18 cm, and also with mass moment of inertia I, of 13x10° kg.m?.
The initial energy E, on the flywheel is 850 J, 500 J at a1, 450 J at az, 550 J at az, 350 J at a4, 450 J at
as and 400 J at as. By using all the information given,
a) Compute the Energy at A, B, C, D, E, F and G
b) Estimate the Maximum fluctuation of energy, AE
c) Calculate the Radius of gyration, k of the flywheel
d) Examine the Mean kinetic energy, E of the flywheel
