英语翻译
Examlple 1.As shown in Figure 6.21 a cylindrical barrel is half full of water,being on an end.Suppose the height of the barrel is H,the radius is R,and the specific gravity is B .Calculate the total force acted on the bottom of the barrel by the water.
Solution.The force to be computed here depends on the pressure P exerted by the water,such that
P=B*(H/2)
where (H/2) is half of the height of the barrel,considering the barrel is half full,and the area A of an end of the barrel is
A=пR2(R的平方)
The total force exerted by the water on the bottom of the barrel is
..........(打不出来,不翻译了)
If the culindrical barrel in Exmaple 1 is lying on its side ,the calculation can be more complicated.
那两个式子用英语怎么说,也麻烦翻一下了
请不要给我百度,google 翻译来糊弄我,灌水的人也不要来,复制我问题就回答的白痴也不要来。不会翻译就不要来,我又不是不给分,我尊重你们,你还能尊重我一下?
(希望楼主满意~^ ^ 我直接写译文了哦~)
例题1.如图6.21所示,一直立的圆柱形的桶装了半桶的水.假设桶高为H,桶的底面半径为R,相对密度为B.计算桶底面所受的总压力.
总压力由桶底面所受的压强P决定,因此,P=B*(H/2),(H/2)表示桶高的一半.
假设桶装满了水,桶的底面积A表示为 A=пR2(R的平方),
桶底所受的总压力就是.
如果例题1中的圆柱形桶不是直立的而是以侧边着地横着放,运算将更为复杂.
至于楼主问的关于两个式子的读法,是这样的:
P=B*(H/2)读作:P equals to B times half of H
A=пR2读作:A equals to п times R square
当然每个人的习惯不同对式子的读法也可能不同,有些人读得更为简炼些,有些人用其他句式表达,但这样读肯定是没错的啦,楼主可参考哦~
