Features: 1.Suitable for ordinary middle schools, technical secondary schools when students conduct experiments or group experiments. 2.Demonstrate composition and decomposition of forces. 3.Simple structure, easy to operate and clean. 4.The effect of several forces acting together can be replaced by a force called the resultant force of several forces. The process of finding the component force of a known force is called the decomposition of force. 5.If several forces work together on the object to produce the same effect as a force acting on the object alone, then the force is called the resultant force of these forces, and these forces are called component force of the force. force. Resultant force and component force are an equivalent substitute relationship. specification:Condition: Brand New Item Type: Physical Experiment Apparatus Material: Metal, Plastic PackageList:1 x Dynamometer Regulator1 x Scale Division Coordinate Plate1 x Force Combined Ring2 x Pulley Clip1 x Base1 x Line1 x Bar2 x Screw Note1. When using the instrument, it must be placed steadily to prevent tilting from affecting the experimental results. 2. During the experiment, adjust the projection of the concentric ring and the hanging line of the concentric ring and the coordinate disk, and you must look up on one side to reduce the experimental error. 3. Prevent organic solvents from contacting the instrument to avoid damage to the surface.
