Question

求好心人翻译一下英语

(i) Let two corridors of width a and b, respectively, intersect at right
angles. Then the length of the longest thin rod that will go horizontally
around the corner is (a^ 2 / 3 + b ^2 / 3 )^3/2.
(ii) The length of the shortest thin beam that can be used to brace a wall,
if the beam is to pass over a second wall (of negligible thickness) that is b units
high and a units from the first wall is (a^ 2 / 3 + b ^2 / 3 )^3/2.

Answer 1

自从一艘来自英国的船于1770抵达澳大利亚，原住民的生活开始改变。许多原住民在与英国人的战争中被杀。更多的欧洲人来到这片土地，他们开始夺取原住民的土地。这些欧洲人也带来了令原住民致命的疾病。因此现今仅有300000名原住民仍生存在澳大利亚。

(i) Let two corridors of width a and b, respectively, intersect at right
angles. Then the length of the longest thin rod that will go horizontally
around the corner is (a^ 2 / 3 + b ^2 / 3 )^3/2.
(ii) The length of the shortest thin beam that can be used to brace a wall,

（i）让宽度为a和b的两条走廊分别相交
角。 然后最长的细棒的长度将水平移动
拐角处是（a ^ 2/3 + b ^ 2/3）^ 3/2。
（ii）可用于支撑墙壁的最短薄梁的长度，
如果光束通过b单位的第二壁（可忽略的厚度）
高和一个单位从第一个墙是（a ^ 2/3 + b ^ 2/3）^ 3/2。
