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. If the masses are balanced by two counter-masses named X and Y rotating with the shaft acting at a radius of 0,3 m and placed at 0,3 m from each bearing centre. 1.Draw a diagram illustrating the position of masses on the shaft. 2.Calculate the dynamic force in Newtons 3.Calculate the moment acting on the shaft in Newton-metre.
