Exact solution of the Mass Spring system in the Abaqus software

In this example we intend to simulate the Exact Solution of the Mass Spring system in the Abaqus software. As you observe in this picture, the steel bar has been hinged at point O, and two springs have been fastened to the top of the bar, so the bar can only rotate about point O

The initial angular velocity of the whole bar is 7 Radian/second

The purpose of this analysis is to obtain the Equation of motion of the mass spring system using the Abaqus software and compare the results gained from that with those obtained from the Exact solution
