5 MECHO010 2021/22 2. Figure 2 shows a mass-spring-damper system. The ordinary differential equation is given in Egn. 1 in association with the system. fft) m E x(t) Figure 2: Mass-spring-damper system. mx(t) + bx(t) + kx(t) = f(t) Egn. 1 a) Determine the transfer function considering the input force f(t) and output displacement x(t). [1 mark] b) Table 1 gives values for the mass m, damping coefficient b and spring constant k for 5 cases. For each case, answer the following questions: i) Determine the system order, pole location, and stability. ii) Provide an illustration of a step and impulse response.
