Question

อ2 = 135 and 03 = 240 A rotating shaft carries three objects with masses mi = 12Kg m2 = 9Kg and m3 = 7.5Kg at radial distances of r1 = 75mm r2 = 85mm and r3 = 5 mm and angular positons of, = 45 The angular positions are measured clockwise from the veritcal axis. An addirional object with mass ma at radial distance r75mm is added to statically balance the system Identify the correct force palygon showing that the system is statically balanced mir m2r2 m3r3 m4T4 miri m4r4 m3ľ3 m2r2 m2r2 m4r4 m3r3 mi m2 m3 m4 What is the mass (m4) of the additional object 4 which must be added to give static balance? (You can use the graphic or the trigonometric method to answer this question) What is the angular position of the additional object 4 which must be added to give static balance?
