Define all the measurements you know, including specifically the distances and angles. You will need these to perform the necessary calculations. In statics, the perpendicular distance is in units of force called newtons.
Determine the angle of the point in reference to the origin of the axis system in use. You can calculate the perpendicular distance using geometric principles and relationships. The perpendicular distance represents the force you exert on the moment of the point around the origin of the axis.
Replace the direct distance of the point from the origin for the variable d in the equation: Perpendicular distance = d X cos (angle). The direct distance is in meters and will yield newtons for the perpendicular distance. Replace "angle" with the measured angle between the origin of the reference system and the moment of the point. The term cos represents the cosine of the angle.
Perform the calculation to obtain the perpendicular distance of the moment of the point.
