翻译:圆锥体的底面半径为6,一个平行于底面的截面半径为4,这个截面与地面的距离为8,这个圆锥体的高是多少?
设圆锥体的高度为x,根据两个椎体相似得到方程:6/4=x/(x-8)
解得x=24

翻译:对一个圆锥体底半径为6和半径的一个平行的横截面为4。如果基地和横截面之间的距离为8。圆锥体的高度是多少?
根据题可设圆柱的高为H, 则有H/(H-8)=6/4 所以 H=24 因此该题选(e)

angular momentum...who is rotating?
I think what I did was right.refer to 3,angular momentum is a MAYBE,not a must.I used momentum,which is in the list as well.
Firstly,energy is NOT conserved,because there is impact dissipation.
Secondly,angular momentum is conserved,but not useful,because the system is symmetric and no fixed point for rotation.
Finally,momentum is conserved,and the only way I can think of is F=dp/dt for the force.and of course I could be wrong,so just for reference:
F=dp/dt=d(mv)/dt=v d(ρ pi R^2 L)/dt=v ρ pi R^2 dL/dt =v^2 ρ pi R^2
Here's the complete problem.
1.The problem statement,all variables and given/known data
A uniform,spherical planet of mass M and radius R moves SLOWLY with an essentially uniform speed v through a cloud of interstellar dust particles,whose density is ρ.The dust particles are attracted towards the planet,and some of them would eventually fall onto its surface.
Find the resulting retarding force on the planet due to the dust cloud.
Since the planet moves slowly,initial speed and final speed can be assumed to be the same
2.Relevant equations
Angular momentum => Li = Lf
Momentum => Pi = Pf
Energy including
Potential energy = GMm/R2
Kinetic Energy = 1/2 (mv2)
3.The attempt at a solution
The clue is to use conservation of momentum,angular momentum,and energy.
Solution should be in terms of speed v,radius R,mass M,and density ρ

英语翻译
32.10 Transverse radius rods
Where coil,torsion bar or air springs are used,which of course cannot locate the axle,other measures have to be introduced.Two such arrangements are illustrated in Figs 32.8 and 32.9,where transverse radius rods A,usually termed Panhard rods,are employed - to take the lateral loads - in conjunction with a single combined torque-thrust member B of the type illustrated in Fig.32.6.With the arrangement of Fig.31.8,the Panhard rod is parallel to the axle and therefore can have simple pivots at its ends.The advantage in Fig.32.9 is that the Panhard rod is longer and therefore has less tendency to pull the axle laterally,as it moves up and down.On the other hand,its pivots must be rubber bushed,unless it can be arranged to lie parallel to the axle.

1) V = (1/3)πr^2 h
如果高度不变,只是半径增加,那么方程两边对时间求导得,
V' = (2/3)πrr' h = (2/3)π(6)(1/2)*9 = 18π cm^3/sec
2) A = 2π r^2 + 2π r h
限制条件:V = π r^2 h = 16π
=> h = 16/r^2 代入面积表达式,
A = 2π r^2 + 2π 16/r
对r求导,并令A' = 0,
2r - 16/r^2 = 0
r = 2 inches
h = 16/r^2 = 4 inches

应该是形容飞行类的运输机械吧?翻译是:净重最大为225千克,高于地面500英尺(的飞行距离),3000里的半径

2.在一口深的矿井的底部大气的密度与在地的表面大气的密度相比较将会怎样
因为密度=质量/体积,在矿井底部压强大,导致体积变小,所以在空气质量不变的条件下,密度会增大

这就是求一个等边三角形的回转半径.
先求它的极惯性矩,对重心求.

这个知道回答是教你求对一个轴的惯性矩.
极惯性矩就是两个方向相加bh3/18
回转半径就是 极惯性矩除以面积的平方根
所以就是 √(bh3/18/(bh/2))=√(h2/9)
所以回转半径为h/3,h=√3*a
所以回转半径为 √3*a/3

Sharp 突然的 或是瞬间的意思
drawn 扭曲的 扭转
radius 半径
to be Max.of R0.2mm" 最大为0.2mm
这回明白了吧
翻译出来就是:瞬间扭转半径最大值为0.2mm"

B 25kilonewtons.
万有引力公式:F=G*(M地m卫)/r2
G=6.67*10^-11
M地=5.976*10^24 kg
M卫=100000N=10000kg
r=12800km=1.28*10^7 m
代进去化简算出来约等于24.32.

你这个图是不是6个小圆与大圆围着一圈相切,然后中间一个小圆与其他六个小圆相切,未涂色部分是除了小圆外的部分.如果是这样的话,大圆半径就是3cm(一条直线上的三个小圆圆心相连延长就是直径,∴大圆直径=3×小圆直径...

所有的循环都可以改为递归.
只是这里用循环,判断点到圆心的距离即可,
速度/稳定性/资源使用/可读性 等都挺好.
觉得没必要为了递归而递归.

选A.
C++标识符要求:
1、必须由数字、字母或下划线构成,不能有其它字符;(排除B)
2、必须是以字母或下划线开头;(排除D)
3、字母大小写敏感,即大写字母和小写字母不是同一个标识符,例:num和Num是两个不同的标识符;
4、不能是C++本身的关键字或保留字,也就是在C++中有固定含义的标识符,比如else;(排除C)
5、标识符长度任意,但有些操作系统会有一个长度上限.
