Question
![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 m². 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.)
