Abstract
The utility model discloses a dual force balance demonstration device consisting of a demonstrating plate, two equal poises, a base, a support rod and a panel installed on the support rod. Both sides of the panel are provided with two symmetric pulleys on the same level. A horizontal line is carved below the pulleys. Both sides of the demonstrating plate are respectively provided with a row of small pores. The poise suspended lines on both sides can be hung on the small pores at relative side randomly. The demonstrating plate suspends in the air with the support of the two pulleys. The utility model can visually demonstrate the circumstance of dual force balance and help children and juvenile to better understand the concept of the dual force balance.
Description
Technical field
The utility model relates to a kind of science popularization teaching demonstration device, is the balance between two forces apparatus for demonstrating in a kind of mechanics teaching specifically.
Background technology
Balance between two forces is one of basic content in the physical mechanics teaching, is the important content in the mechanics teaching.How to go out the balance between two forces phenomenon be to need the problem that solves in the teaching in ocular demonstration.
The utility model content
Technical problem to be solved in the utility model is to remedy the blank that prior art exists, and a kind of apparatus for demonstrating of energy visual pattern ground demonstration balance between two forces phenomenon is provided.
The utility model balance between two forces apparatus for demonstrating is made of quality counterweight, pedestal, beanpoles such as demonstration board, two and the panel that is installed on the beanpole; The panel both sides are symmetrical arranged two pulleys on same level, a horizontal line is carved with in the below of pulley; Row's aperture is respectively established in the demonstration board both sides, and the counterweight suspension wire of both sides can be suspended on arbitrarily on the aperture of a side separately, by two pulley support demonstration board is suspended in the air.
The gravity of two counterweights is turned to by pulley, becomes the pulling force to demonstration board, makes demonstration board rotation to reach two power balance gradually, and final two power are on the same horizontal line, by with panel on the horizontal line carved can observe equilibrium of forces.
The utility model balance between two forces apparatus for demonstrating can be demonstrated the balance between two forces phenomenon in visual pattern ground, can help children to understand the balance between two forces notion better.
Description of drawings
Fig. 1, be structural representation of the present utility model.
Embodiment
