a) A mass of 10 kg is fixed in the middle of a spring of stiffness 5 N/mm, as shown in Figure 2.0. Calculate the natural frequency of the system. 2k m 2k Figure 2.0 (10 MARKS) b) A uniform thin rod, as shown in Figure 2.1, has a mass of 1 kg and carries a concentrated mass of 2.5 kg at B. The rod is hinged at A and is maintained in the horizontal position by a spring of stiffness 1.8 kN/m at C. Find the frequency of oscillation, neglecting the effect of the mass of the spring.
