The turning moment diagram for the engine is drawn to the following scales: Turning moment, 1 mm = 1000 N-m and crank angle, 1 mm = - 6°. The areas above and below the mean turning moment line taken in order are : 530, 330, 380, 470, 180, 360, 350 and 280 mm². The mean speed of the engine is 150 r.p.m. and the total fluctuation of speed must not exceed 3.5% of mean speed. Determine the diameter and mass of the flywheel rim, assuming that the total energy of the flywheel to be 15/14 that of rim. The peripheral velocity of the flywheel is 15 m/s. Find also the suitable cross-scetional area of the rim of the flywheel. Take density of the material of the rim as 7200 kg/m³. [Ans. 1.91 m; 8063 kg; 0.1866 m²]

H.W (1): An engine flywheel has a mass of 6.5 tonnes and the radius of gyration is 2 m. If the maximum and minimum speeds are 120 r. p. m. and 118 r. p. m. respectively, find maximum fluctuation of energy. [Ans. 67. 875 kN-m] H.W (2): The turning moment diagram for a multicylinder engine give maximum fluctuating of energy 7914 N.m when the engine is running at 150 r.p.m. If the mass of the flywheel is 1000 kg and the total fluctuation of speed does not exceed 3% of the mean speed, find the minimum value of the radius of gyration.

Unlike the common V6 engine, Subaru engines contain pistons that are horizontally opposed (see Wikipedia for more info). Luckily for us, this also makes for an interesting dynamics problem! At the instant shown, the crank arm's angular velocity is waB = 2,000 rpm (rotating clockwise) and the angle 0 = 40° with respect to the horizontal. Length of bar AB is r1 = 3 in. and the length of bar BD is r2 = 8 in. a) Clearly define coordinate systems for each link and write transformation arrays for each. b) Compute the velocity of point B in ft/s. Express your answer in rectangular coordinates. [Ans. to Check: 33.66 i– 40.11 j ft/sec] c) Determine the magnitude of the speed of the piston P in ft/s. Note: all answers should be positive since we only want to know the magnitude of the speed, not the direction (the piston can only move in the horizontal direction). [Ans. to Check: 43.6 ft/s] r2 10 B
