The joint at which they are attached can exert both parallel and normal forces (otherwise, the beam and support cable wouldn't be "attached," they would slide down the wall). | |

In general you expect both normal and parallel forces. If the parallel force is purely frictive then it has the usual relationship with the normal force, of course. | |
