A student has written a mathematical model for a rotational mechanical system without gears and some data were missing as shown below: [4s² + 2s +5 -25 as 0 -2s 3s² + 4s +6 (1+B) 0 -6 3s +6 [0₁(s)] O₂ (s)= 0 030 03(s) 0 Vo What are the values of a and B? 2. What is the degree of freedom of the system? 3. Sketch the expected rotational mechanical system and show thetorque, angular displacements and all values of inertias, springs, and dampers on the sketch with 35²+45+45+8 their units. 180 (4)
