    An end moment \(M\) is considered positive if it tends to rotate the member clockwise and negative if it tends to rotate the member counter-clockwise. The rotation \(\theta\) of a joint is positive if its tangent turns in a clockwise direction. The rotation of the chord connecting the ends of a member (\(\frac{\Delta}{l}\)), the displacement of one end of a member relative to the other, is positive if the member turns in a clockwise direction.
