A prop shaft of a heavy duty truck has two bearings which are positioned at 3 meters from each other. The shaft must rotate 30 rad/s when the truck travels at the speed of 40 m/s. Such a shaft carries two masses of 10 kg and 5 kg acting at the extremities of the arms 0,45 m and 0,6 m long, respectively. The planes in which these masses rotates are 1,2 m and 2,4 m, respectively, from the left end bearing supporting the shaft. The angle between the arms is 60 degrees.
