Tools/raw materials:
1, ice cream stick
2. Emulsion
Step 3: ruler
Step 4: nuts
Note: the weight of each nut should be weighed in advance, so as to weigh the weight to be weighed.
Second, draw a line in the center of the ice cream stick that has been cut off in half.
The line drawn at the incision is used as a reference line for grinding ice cream sticks.
3. Use a ruler to find the midpoint of another ice cream stick.
Draw a reference line in its center, as shown in the figure.
Fourth, stick two ice creams together vertically with latex.
Make the baseline completely coincident and make a hole in the ellipse of the ice cream stick.
5. Nail a nail in the middle of the longer ice cream stick.
This will make it stronger, and a lifting ring is installed at the top.
6. Hang a heavy object on the nail.
It will always be perpendicular to the ground and will play a reference role in measurement.
Seven, hang a clip in the two holes of the ice cream stick.
The two trays can be made of plastic flat bottom for placing heavy objects.
Eight, balanced production completion
Now you can use it to weigh things. You can use nuts as weights, put them at one end of the balance and put the things to be weighed at the other end.
Extended data
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.
Modern scales are more and more accurate, more sensitive and more and more kinds. As we all know, there are ordinary balance, analytical balance, constant analytical balance, micro analytical balance, semi-micro analytical balance and so on.
