a) L Question 7: A massless beam ABC of span L and con- stant flexural rigidity EI is simply supported at A and C, and it supports a mass concentrated at the midspan point B, as shown in Figure a). The natural frequency of this В El A system is expected to be 25 rad/s. However, the measured b) natural circular frequency is found to be only 23 rad/s, the lower value being ascribed to flexible supports at A and C, k Figure b). Calculate the stiffness k of the beam support k bearings as a fraction of the beam stiffness.
