3.1. Use the Routh-Hurwitz method of determinants to investigate the stability of a system characterised by the transfer function G(p)=3p4+6p3+2p2?3p+4p?1? 3.2. A system with input u(t) and output x(t) is described by the differential equation x???+3x??+4x?+2x=u??2u Use Laplace transforms to determine the impulse response of the system and discuss the progress of the response as t?? and comment about the stability of (11) the system Question Four [12] 4. The sag of a horizontal beam of length 10m is described by the differential equation dx4d4y?=50000kH(x?5)?,k?R,y(0)=y?(0)=0,y??(0)=40003?,y???(0)=?100001? 4.1. Use Laplace transforms to determine the deflection equation for the beam (8) 4.2. Compute the sag when x=8m,k=?1000, discuss the results and then determine the bending moment when x=7m and k=1
