The embodiments herein provide a beamer board for measuring length and comparing weight of two identical objects including fishes. The beamer board acting as a culling system comprises an elongated beam, a first attachment, a slot and a pair of notches. The elongated beam comprises several measurement marks along a length direction for measuring a length of the fishes. The first attachment extending from the beam acts as a starting point for measuring the length. The slot is provided at center for hanging the beam on a holder. The slot act as a fulcrum balance point for balancing the beam. The pair of notches is configured for hanging the objects for comparing the weight of the fishes. The fishes are hanged on the pair of notches using any cull markers available in the markets.

An absolute mass balance determines an absolute mass of an object and includes: a dual diameter wheel including: a balance fulcrum; and a balance beam disposed on the balance fulcrum and including: a main mass arm and a counter mass arm; a main mass receiver that receives the object; a main magnet system including: a first main coil that produces a first magnetic field; a second main coil that produces a second magnetic field; and a permanent magnet that produces a third magnetic field that interacts with the first magnetic field and the second magnetic field; a displacement measuring system that provides a null position of the dual diameter wheel and measures a velocity of the main magnet system; and a driving motor including: an eddy current damper that provides a constant velocity of the main mass receiver; and a counter mass magnet system.

A torsion balance is provided which includes a twisting wire and a reflector. The twisting wire is a suspended carbon nanotube. The reflector is hung on the twisting wire. The reflector further includes a film, a first reflecting layer, and a second reflecting layer; and the film includes a first surface and a second surface opposite to the first surface, and the first reflecting layer is located on the first surface and the second reflecting layer is located on the second surface.

This invention involves a balance scale with a base, a balance arm support, a balance arm, a pointer with a counter-balance, and a movable label plate containing descriptions. The balance arm has a tray on each end, where one tray holds an article representing mankind with sin, and the other tray holds an article representing the redemptive work of Jesus Christ. The articles on each tray are of equal or approximately equal weight. The scale rotates when the weight of the articles are added to or removed from the trays, and the scale rotation will determine which description the pointer will point to. This invention can be used as a Christian teaching aid showing the benefit of choosing to accept the death of Christ as payment in full for our sins, along with showing the consequence of our refusal to accept the death of Christ as payment for our sins.
