WebJul 1, 2024 · In GD&T, perpendicularity tolerance is usually used to control either two 90° surfaces or an axis in relation to a particular reference point on a cylinder. At Metal Cutting, we typically measure perpendicularity in terms of a part in relationship to its end cut, comparing the side of a rod, tube, or wire to the end cut we put on that part. WebEquipotential surfaces have equal potentials everywhere on them. For stronger fields, equipotential surfaces are closer to each other! These equipotential surfaces are always perpendicular to the electric field direction, at every point. Created by Mahesh Shenoy.
