6 A3m long and 1 m wide uniform rigid platform with mass 100 kg is shown in Figure 6. 3m 2m 20kg Figure 6 The platform carries a small central load of 20 kg and is hinged along a short side at . It is supported in the horizontal position by two springs symmetrically placed at P and Q, with stiffness of 20000 N/m and 5000 N/m respectively. Find the natural frequency of the platform about its hinge.
