Sir.. one important query please ... wooden fibres are inclined 20 degree to horizontal, so 200lb horizontal component will cause elongation of those fibres and there will axial/normal due to internal force V. V should cause axial and N should cause shear.. your advise please. thanks and regards.

why didn't we include the other 200lb force in our summation of forces in the x-direction?
