tThe bob of a pendulum swings through a circular arc of constant radius. At what point of the swing does the cord holding the bob exert the greatest entripetal force on it?

You are talking about what is called a conical pendulum. With the bob going in a circle, the centripetal force and the cord tension are constant in magnitude, but merely change direction.
