The teaching aid of solution is less, and difficulty is added to giving lessons.
Utility model content
Technical problem to be solved in the utility model is：A kind of synthesis of power is provided and apparatus for demonstrating is decomposed, power is solved
Synthesis with decomposing indigestible problem, teacher gives lessons rare problem.
The technical scheme that the utility model is used by solution the problem of set forth above is：
A kind of synthesis of power is with decomposing apparatus for demonstrating, including endless glide 1, tensiometer 2, drawing board 3, guider 4, conjunction
The line of force 5, component line 6, counterweight ring 7 and counterweight group 8, endless glide 1 set drawing board 3 below, and the tensiometer 2 passes through link
14 are arranged in the middle of endless glide 1, and guider 4 is arranged in endless glide 1, and the one end of line 5 is connected with tensiometer 2 with joint efforts, are closed
The other end of the line of force 5 is connected with the one end of component line 6, and the other end of component line 6 bypasses guider 4 and is connected with counterweight ring 7, counterweight group 8
It is hung on counterweight ring 7, the guider 4 includes sliding block 9, pulley 10 and hollow shaft 11, sliding block 9 is arranged on endless glide 1
On, pulley 10 is arranged on sliding block 9 by hollow shaft 11.
The described upper end of endless glide 1 sets suspension ring 13, is convenient for carrying, hangs, is easy to explain at any time.
Described guider 4 is at least 2 groups, and the component line 6 is identical with the number of guider 4, can demonstrate multiple
The decomposition of the synthesis of power or power in multiple directions.
Described guider 4 is fixed in endless glide 1 by standing screw 12, can fixed guide position.
Described standing screw 12 is directed to device 4 through hollow shaft 11 and is fixed in endless glide 1.
Operation principle of the present utility model：When demonstrating the synthesis and decomposition of power, it is directed to setting position and adjusts, by counterweight
Group is hung, and the junction of component line and line with joint efforts, which is drawn, takes end points, takes component line segment along component line drawing, phase is intercepted according to counterweight group
Whether the length answered, picture takes parallelogram, draws diagonal, measures length, calculates with joint efforts, it may be verified that make a concerted effort with line with joint efforts to refer to
Overlapped to the direction of end points, whether the size made a concerted effort directly reads that value is identical with tensiometer, can directly verify parallel four side of power
Shape rule.
The beneficial effects of the utility model are：1st, it is simple in construction, it is easy to operate；2nd, demonstrating visual, student is readily appreciated that,
Teacher gives lessons simply；3rd, checking parallelogram law can be directly carried out, it is readily understood；4th, it is convenient for carrying, hangs, is easy to say at any time
Solution.
