由于斜面终端没有挡板,实验时,若不用手阻挡,则小车每次运动到斜面终端都要对滑轮及其支架进行撞击,并且小车也经常甩落在地下.因此,每班每次实验结束,仪器都要损坏2至5套,严重地影响了下一班实验的顺利进行.为此,我们在斜面终端加一挡板,使仪器完好率大为提高.现将制作方法及数据介绍如下:1.将1—2mm 厚的白铁皮按图所示的尺寸剪好,钻好孔.在虚线处弯成直角,弯好的挡板呈
Because there is no baffle slant terminal, the experiment, if you do not hand block, the car every time you move to the bevel end of the pulley and its support should be hit, and the car is often thrown in the ground .Therefore, the end of each experiment in each class , The instrument must be damaged 2 to 5 sets, a serious impact on the next experiment smoothly.To this end, we add a bezel at the bevel terminal, so that the instrument intact rate greatly improved. Now the production methods and data are described below : 1. The 1-2mm thick white metal cut the size shown in the figure, drill a good hole in the dotted line at a right angle, curved good bezel was
