If the beam AD is loaded as shown in Figure Q4(a), determine the horizontal force P which must be applied to the wedge in order to remove it from under the beam. The coefficients of static friction at the wedge's top and bottom surfaces are µCA - 0.25 and HCB = 0.35, respectively. If P = 0, is the wedge self-locking? Neglect the weight and size of the wedge and the thickness of the beam.

Question
a) If the beam AD is loaded as shown in Figure Q4(a), determine the horizontal force P
which must be applied to the wedge in order to remove it from under the beam. The
coefficients of static friction at the wedge's top and bottom surfaces are µCA = 0.25 and
HCB = 0.35, respectively. If P = 0, is the wedge self-locking? Neglect the weight and size
of the wedge and the thickness of the beam.
