(Q1) A uniform beam, of mass 31 kg/m run, is simply supported on a span of3.6 m. Taking EI for the beam as 7 MN.m2, calculate the frequency oftransverse vibrations.This frequency is to be reduced by 40% by fixing three equal masses tothe beam, at the mid-point and the quarter points. Calculate how muchthese masses should be.

EI for the beam is 110 MN.m2. The mass of thebeam itself may be neglected.Determine the frequency of transverse vibrations of the beam in avertical plane:a) very roughly, assuming the whole load to be concentrated at itscentre of gravity.b) more accurately, by treating the load as three equal concentratedloads applied at suitable points.
