Q10:- The turning moment diagram for a four stroke gas engine may be assumed for simplicity to be represented by four triangles, the area of which from the line of zero pressure are as follows:- suction stroke=0.45 *10 m², compression stroke= 1.7*10* m², expansion stroke= 6.8*10³ m? and the exhaust stroke =o.65*10* m². Each square meter of area represents 3MN.m of energy. Assuming that the resisting torque to be uniform, find the mass of the rim of the flywheel required to keep the speed between (202-198) rpm. The mean radius of the rim is 1.2 m.

Q10:- The turning moment diagram for a four stroke gas engine may be assumed for simplicity to be represented by four triangles, the area of which from the line of zero pressure are as follows:- suction stroke=0.45 *10 m, compression stroke= 1.7*10 m', expansion stroke= 6.8*10³ m? and the exhaust stroke =o.65*10 m2. Each square meter of area represents 3MN.m of energy. Assuming that the resisting torque to be uniform, find the mass of the rim of the flywheel required to keep the speed between (202-198) rpm. The mean radius of the rim is 1.2 m.
