本人有如下的问题
第一,有关外形的问题,它的外形是不是一定要四个半圆的形状,否则认为不合格,如果是其它的形状可以吗
第二,关于结构中实验的问题
1,第12章 12.9.4 是如何做的
Position a pin on the fixed anvil of the apparatus, as shown in Figure 32, with its contact surfaces in the
horizontal plane. Apply a force of N to the movable anvil by any convenient method such that the
pin is strained at a rate not exceeding 10 mm/min.
这句话是如何理解的,该怎么做,能否解释一下
2 就是保险丝座和pin是不是不能用螺丝的形式固定
谢谢各位大吓能够指点,谢谢

The outline of the plug shall not exceed the dimensions shown in Figure 4a) for a distance of not less than 6.35 mm from the engagement surface and within these dimensions there shall be no axial projection from the engagement surface of the plug, except that at a distance more than 6.35 mm from the
engagement surface the outline of the plug may exceed the dimensions shown in Figure 4a) in the plane of
the earth pin and in the plane of the cord entry to facilitate the removal of the plug from the socket.
这句话很那理解,6.35mm到底指的是什么,能够举一个实例来解释一下
