A horizontal beam ABCD is carried on hinged supports and is continuous over three equal spans each of 3m. All the supports are initially at the same level. The beam is loaded as shown. Plot R.M.D> for the beam if the support 'A' settlers by 10mm, 'B' settlers by 30mm and 'C' settlers by 20mm. Use M.D. method. Take E=2.0×105 N/mm2, I=2.4×106 mm4.
