A shaft having length equal to 10 m and diameter equal to (50+ 01) mm is simply supported at both ends. The shaft carries four masses (150 + 01) kg, (200 + 01) kg, (250 + 01) kg and (300 + 01) kg. These masses are located at a distance of 1.5 m, 2.5 m, 5.5 m and 7.5 m from the left hand side support, respectively. The modulus of elasticity, E, for the material of the shaft is 200 GN/m² and mass density for the shaft material is 7500 kg/m3. Determine critical speed of the shaft in revolutions per minute for the following two cases: 1. Effect of the mass of the shaft is neglected. 2. Effect of the mass of the shaft is considered. What is the usefulness of the answers determined in this problem?
