Q3 Figure Q3 shows a spring-mass system composed of three masses suspended vertically by a series of springs. To develop a mathematical model of the spring-mass system, Newton's second law can be employed in conjunction with force balances. For each mass, the Newton's second law can be expressed as: d'x - = F,- Fy m dt? 4* is the acceleration of an object, E, is downward force dt? where m is the mass of an object, and Fy is upward force. (a) Show that when the system eventually comes to rest (steady state), the displacements of the masses can be expressed as 3kx, 2kx, -2kx, + 3kx, = mg ky, + ky3 (b) Write the system of linear equations in Q3(a) in complete matrix form. (c) Solve the system of linear equations in Q3(a) using Doolittle method. Given k = 10kg/s2 g = 9.81m/s² , m is the first two digits of your matrix number, m is 2 m2 the last two digits of your matrix number and " + 5.5 . M1=20 M2=01

Please answer the given question as soon as possible. Thank you very much.

(a) Explain the meaning of spring force and the graph of spring force against position (b) The 8735 kg helicopter is takes off vertically with its rotor exerting a constant upwardthrust of 117 kN. Determine how far it has risen if its velocity is 11 m/s. In Figure 4 (c), the 30 N block is moving up the smooth inclined surface at velocity and constant force of 2 m/s and 15 N, respectively. (i). Draw the kinetic diagram of all forces exerted on box (ii). Calculate the velocity of the block when it has moved 1 m up the surface from its present position. (c)
