Question 4 Three masses are placed on a shaft angled at 120° from each other. The shaft is supported on ball bearings at its ends and 500 mm long, meaning each mass is placed 100 mm apart from one another and from the supports. A slight imbalance is present, as the masses have a mass of ma = 1.3 kg, mg = 1.8 kg and mc = 1.65 kg, respectively, and each mass rotates at a distance of 100 mm from the centre of the shaft. Determine: a) The out of balance force when the angular rotation is 1500 rpm. (25 marks) b) The out of balance force on the other support when the angular rotation is 1500 rpm. (10 marks)
