Distance of Deflection from End A is the distance at which the deflection occurs in a beam or column, measured from one end of the beam, designated as End A. And is denoted by x. Distance of Deflection from End A is usually measured using the Millimeter for Length. Note that the value of Distance of Deflection from End A is always negative. Typically, the value of Distance of Deflection from End A is greater than 0.
