Question

Don't necessarily need this to be solved using MATlab like it says but if you could be clear about what is happening in each step, I think it'd be easier for me to reproduce in MATlab. Thanks.

Problem 2. points 20 - Use MATLAB Consider the three mass-four spring system in Fig. 1. Determining the equations of motion from Σ Fx max, for each mass using its free-body diagram results in the following differential equations k2 mm1 m1 0 m2 m2 m2 m3 m3 30 N/m, and m m2m 2 kg. Write the three where kk4 10 N/m, k2-k3 uations in matrix form: 0- [Acceleration vector [k/m matrix [displacement vector x 1. At a specific time when 0.05m, r2 - 0.04m, and r3- 0.03m, this forms a tridiagonal matrix. Solve for the acceleration of each mas:s 2. At another specific time the accelerations of the three masses are i 5m/s2, i2 -4m/s2, and 2m/s2. Solve for the displacement of each mass Figure 1: Figure for problem 2.
