2. A simply supported beam of negligible mass and of length l, has three bodies each of mass m attached as shown. The influence coefficients are, using standard notation: 11=3l3/256EI21=3.67l3/256EI31=2.33l3/256EI22=5.33l3/256EI. Write down the flexibility matrix, and determine by iteration the frequency of the first mode of vibration, correct to 2 significant figures, if EI=10Nm2,m=2kg, and I=1m Step by Step Solution
