Specification Brand : VERIMP BulletPoint1 : Purpose: It is a commonly used experimental tool for physical statics experiments in middle schools. It can verify the parallelogram rule of forces through the synthesis of common point forces. BulletPoint2 : The experimenter consists of flat plate (rubber bottom plug, bolt), white paper, spring balance (2 pieces), string, thumbtack, rubber band, etc. BulletPoint3 : The structure of the instrument conforms to the actual conditions of the force system and is improved and refined on the basis of traditional experimental instruments. BulletPoint4 : The experimenter uses a panel as the experimental base, which is more beautiful and stronger than the wooden base. BulletPoint5 : A rubber bottom plug is embedded on the base plate to make it easier to fix the thumbtacks. At the same time, the rubber strip is fixed with bolts, which is firm and easy to operate. The instrument has a simple and novel structure and is easy to operate.

(1) Place the panel flat on the table, lay a piece of white paper on the panel, and secure the white paper with thumbtacks and rubber bottom plugs. (2) Fasten one end of the rubber strip to the bolt (point A), tie two strings to the other end of the rubber strip, and tie a noose to the other end of the string. (3) Use two spring scales to hook the rope sets respectively, and pull the rubber strip at an angle to each other, so that the rubber strip stretches and the node reaches a certain position 0 (see figure). (4) Use a pencil to note the 0 o'clock position and the directions of the two strings, and read the indications of the two spring balances. (5) Use a pencil and a scale to draw a straight line on the white paper from 0 point along the direction of the two strings, draw a diagram of the two forces F, F, according to a certain scale, and use the parallelogram rule to find the resultant force F . (6) Use only one spring balance, pull the node of the rubber strip to the same position 0 through a string, read the indication of the spring balance, note the direction of the string, and draw a diagram of F' of this force according to the same scale. Show. (7) Compare the magnitude and direction of F' with the resultant force F obtained using the parallelogram rule, and observe whether they are equal.
