摘要
杠杆平衡条件探究仪采用了互变杠杆,既可以探究直杠杆的平衡条件,又可以探究曲杠杆的平衡条件,较易得出较为普遍的结论.该仪器设计了限位器,保证了仪器的稳定性;设计平衡指针和平衡角度盘,直观地显示杠杆平衡时的偏转角度;同时通过力臂标尺可准确地测出动力臂和阻力臂.
A flexible level was designed ,and the balance conditions were explored .Limiter was used to ensure the stability of the device .To directly display the deflection angle when the level bal‐anced ,a pointer and an angle plate were mounted on the device .Ruler of arm of force was used to measure accurately the power arm and the resisting arm .
