The split ring of radius r is rotating about a vertical axis through its center O with a constant angular velocity w. Use a differential element of the ring and derive expressions for the shear force N and rim tension T in the ring in terms of the angle 0. Determine the bending moment Mc at point C by using one-half of the ring as a free body. The mass of the ring per unit length of rim is

2. Consider the Mass-spring system shown in Figure 1. Find the equations of motion for the system where m and g are the masses of the two objects, and A are the spring constants of the three springs. In addition, you are given that l1 and l2 are the equilibrium displacements at which spring 1, spring 2, and spring 3 apply zero force, respectively. Lastly, d is the distance between the two rigid walls. Consider the following data relating a spring's displacement from equilibrium to the force applied by it. Use the data to identify the spring constants k and k1. An excel sheet has been provided in CCLE with the same data provided in the table in order to make it easier for you to transfer data into Python.
