ET2063 Question 1 (25 marks) The system shown in Figure Qi consists of two interconnected masses mi and m. Both springs of stiffness coefficients and have one on their ends attached to non-moving walls. The spring of coefficient and the damper of constant bare placed between the two masses The positions of these masses are represented by Xi and respectively. This system has an external force u, acting on that is considered the input of the system, For the described system find the following: a) Equations of motion [10 marks] b) Transfer function X (8) U(s) [15 marks] x x2 k2 w m2 www kl m2 ww k3 6 ZOO Figure Q1 Page 2 of 6
