The transverse shear V at a certain section of timber beam is 25kN. if the beam has the cross sectio shown in the figure, determine:

The transverse shear V at a certain section of timber beam is 25kN. if the beam has the cross sectio shown in the figure, determine: (a) the horizontal shearing stress in the glued joint 50mm above the bottom of the beam(b)the vertiacal shearing stress at a point 80mm above the bottom of the beam.(c) the magnitude and location of the maximum vertical shearng stress on the cross section
