For the beam shown in Fig. Q4, use the principle of virtual work to determine (1) the vertical deflection at Point C, and (2) the rotation at the right-hand bearing (Point B). The Young's modulus of the material is E = 200 GPa. The cantilever beam has a circular cross section with the second moment of area / = 30 x 106 m²4. The beam is under a uniformly distributed load q=15 kN/m at the AB span and a point force P=27 kN at Point C. The length of AB span is L=9 m and the length of BC span is L₁ =3.6 m. (In this question, we assume (1) the positive direction of a vertical force points upwards; (2) the positive direction of a horizontal force points to the right; and (3) the postive direction of an applied moment is clockwise.)
