Experimental apparatus of coulomb's law  for  high school , New Design!

This instrument is suitable for the high school physics in "electric" about the charge, the coulomb's law, such as teaching content, through a quantitative experiment, the expression of the coulomb's law.
This experiment apparatus is composed of base, beam bracket, beams, electrostatic ball stents, height adjuster, stable, bracket, etc.Base consists of 1590 aluminium alloy profile length is 492 mm, the thickness of the surface 4 mm acrylic and other devices used for fixed installation.Beam scaffolds made from a mix of 2020 aluminum and plastic components, used to put a cross beam, stent with a v-shaped blade, with a plastic dial back.The beam at the left fixed a 30 mm diameter chrome plated ball;Have a balance beam right end installation nut;Middle beam down a metal tool rest, up a scale pointer;Beam as a whole with acrylic material, the right side of the scale, hanging above the thin metal wire (equivalent to swim yards).Electrostatic ball bracket is made up of 2020 aluminium alloy profile, vertical fixed on the base with the left;Stents are installed on the dividing value of 1 mm scale;Electrostatic ball diameter of 30 mm, exterior chrome plated;Through the rod was fixed on the height adjuster.Height adjuster main material is acrylic, built-in spring damping mechanism, the regulator can be stable and accurate in electrostatic ball bracket to move up and down;Regulator on the left side of the installation with fixed screw.Stable support located at the base of the back, made of acrylic, used to make experiments put beams, protect the metal blade.The right side of the bracket is composed of acrylic, is located in the base, used for the experimental operation is convenient adjustment.
