Q4:- It is known the following data of each cylinder in a 2-stroke, in- line, 6-cylinder Diesel engine:- (a) mass of the piston= 0.5 kg, (b) mass of crank pin= 0.1 kg, (c) mass of the connecting rod= 2.5 kg, (d) length of the connecting rod= 525 mm, (e) length of the crank pin= 105 mm, (f) the distance from the crank pin center to the center of gravity of the connecting rod= 110 mm and (s) the axial pitch of the cylinders (from 1 to 6) are (100,100, 150,100 and 100) mm respectively. Calculate the maximum unbalanced effects and the angular position relative to the crank No.1 when the engine runs at 3000 rpm and the firing order is 153624.
