Noted that the components combine so that one of the inclined planes is in compression while the other is in tension.Concrete is strong in compression but weak in tension, and there is a tendency for the concrete to crack on the plane subject to tension should the stress become large enough. The tensile force resulting from the tensile stress acting on a diagonal plane has historically been designated as diagonal tension When it becomes large enough, it will necessitate that shear reinforcing be provided.
