A mass-spring system is shown in Figure Q2 with mı = 10 kg, m2 = 20 kg, kı = (10+P) N/m, k2 = (10+Q) N/m and k3 = (20+R) N/m. =
(c) Determine the natural frequencies of the system. (d) Evaluate the mode shapes of the system complete with the mode shape diagram. Note Q2: The values of P, Q and R depend on the respective 4th, 5th, and 6th digits of your matric number as in the following number format: AD xxxPQR. For example, if your matric number is AD 170154 gives the value P=1, Q = 5 and R = 4, thus the spring stiffness, ki = 11 N/m, k2 = 15 N/m, and k3 = 24 N/m respectively.
