Free undamped vibrations

Whenever an object/system displaces in either side of its equilibrium position with the help of an external/internal means, then the object/system moves regularly or randomly on both sides of its equilibrium position. This motion is called vibration. Generally, there are three types of vibration: longitudinal vibration, transverse vibration, and torsional vibration.

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.

Consider a device consisting of two equal masses of size 5 kg placed along the x axis at x = -3.3 m and x = +3.3 m. The system is spinning as a whole at 7 rad/s about the y axis. A machine at the origin pulls in these masses in closer to the center, so that they are now at x = -1.8 m and x = +1.8 m. As a result of conservation of angular momentum, the spin rate increases. As a result, the rotational kinetic energy also increases, yet energy is conserved. Deduce the amount of work the machine must have done, in J. (Please answer to the fourth decimal place - i.e 14.3225)
