How to balance by hand is simple and convenient.

How to make a balance by hand is simple and convenient. The related methods are as follows: tools/raw materials, knives, scissors, pencils, double-sided tapes, paper cups, colored paper, cardboard and ropes. Methods/steps.

First, two pieces of cardboard, one long and one short, are supported in a triangle. Then stick a rectangular cardboard on it. Then wrap the paper cup with double-sided tape, paste colored paper, and draw some patterns with a pencil to decorate it.

Cut off the excess along the pattern, as does the other paper cup. Cut the paper cup left and right with a knife and scissors. Then put the rope in and tie it.

Then pass the rope through the small hole on the balance. Finally, paste the colored paper on the balance for decoration. This simple manual dynamic balance scale is ready.

The extended information is as follows: Balance, a weighing instrument. The balance beam is supported by the fulcrum (shaft) in the center of the beam, forming two arms, and each arm is hung with a disk, in which an object with known mass is placed in one disk and an object to be measured is placed in the other disk. When the pointer fixed on the beam does not swing and points to the middle scale, the deflection of the pointer indicates the mass of the measured object.

The balance is an equal arm lever. Balance is a weighing instrument, and it is also an instrument for measuring the mass of objects. It is made according to the lever principle. There are two small plates at both ends of the lever, one for putting heavy objects and the other for weighing objects. The center of the lever is equipped with a pointer. When the two ends are balanced, the masses (weights) of the two ends are equal.
