Question

Hi everybody! I need this quick answer, please help!

The beam AB in the figure has length 3L and uniform section stiffness EI. The beam is fixed at A(x=0) and loaded by an upward concentrated force,
P, applied at its free end B(x=3L). A concentrated moment
Q is also applied, as indicated, at distance L from the support at A.

S14Q2_3_2
Obtain a symbolic expression for the vertical deflection at the free end B, v(x=3L), in terms of the given quantities.

v(x=3L)= ?
