Turning moment 1mm = 60 Nm: crank angle, 1 mm = 1° . The turning moment shows the maximum energy that needs to be stored by the flywheel in the unit area is 2850 m² . The flywheel rotates at an average speed of 220 rpm with a total speed change of 2.5%. If the mass of the flywheel is 500 kg, find the appropriate dimensions (inner diameter, outer diameter and thickness) of the flywheel. Given that inner diameter of the flywheel is 0.9 outer diameter and the density is 7.2 Mg/m³ .
FOR FIG REFER THE ATTACHED IMAGE The shaft is massless. A thin attached triangular mass ‘m’ is mounted on the shaft. Rotational speed of the shaft is ω. Neglect weight effect of attached mass. Bearings are at A and B. Take Z- axis along the shaft axis. X- axis is vertically downward. Y – axis is horizontal. Take origin at mid-point on the shaft. Question: Under what practical condition can we justify the neglecting of weight of the attached triangular body?

An older Rolls Royce Ghost is traveling at 25 mph on a roadway with good, dry pavement.The car has a C D = 0.32, 35 ft 2 of frontal area, and weighs 5,445 lb. The wheelbase is 129.7 inand the center of gravity is 25 in above the pavement and 60 in behind the front axle. Thevehicle is traveling on pavement at sea level. The engine produces a hefty 620 ft-lb of torqueand is in a gear of the transmission that provides a gear reduction of 5 to 1 with a 22 in wheelradius and 95% drivetrain mechanical efficiency. If the limo driver needs to accelerate hard inthe Ghost to avoid an accident, what would the acceleration be since it is a rear-wheel drive car?
