A statically indeterminate beam shown in Figure 3 is subjected to distributed live load of w kN/m. Set w = 15 kN/m. Consider A is a fixed support, B and C are roller supports. Support B is settled by 10 mm under the load. Take, modulus of elasticity, E = 200,000 MPa, second moment of area, I = 300 x 106 mm4 and L=8 m.
