The shape of door knobs has been an ever-changing process over the history of architecture and home design. A popular door opener design currently used is a flat, lever-type handle that you can use to open a door. Aside from the aesthetic issues, the flat design is intended to take advantage of what law of electrostatics?
What will be an ideal response?
The flat, lever style of door handle is designed to take advantage of the law of distribution of charges on a curved surface. Old-style door knobs that were round, naturally concentrated charge on the surface of the knob based upon its curvature. Flat lever openers have a lower concentration of charge as the area of curvature is diminished. The net effect is to minimize the shock one receives when the handle is touched. This design feature takes advantage of the law of distribution of charge being greatest where the curvature is greatest.
