... 1.16 or a vector of 1.16 at 180 ° By taking the square root of 0.752 plus 1.162, we get a resultant of 1.38 oz-in Now to get the proper angle: ^4 = 180 ° - tan-1 ^ - 180 ° - 32.8° - 147.2° So we ... Another imbalance of oz-in exists at station 3, located in from the right end, and at an angle of 180 ° from the same reference We want to statically and dynamically balance the rotor, by means of ... 90° The imbalance at station 3, when sensed at station 1, is X 5A2 = % = 0.83 or a vector 0.83 at 180 ° By taking the square root of 2.252 plus 0.832, we find that we must remove 2.41 oz-in Now at...
