  • A slender rod of length L=200mm is held in equilibrium as shown

    一个长200mm的细杆(如图所示)平衡放置,

    with one end against a frictionless wall and the other end attached to a cord of length S=300mm.

    细杆的一端靠在一面光滑的墙上,另外一端系在一条长度为300mm的绳索上.

    Knowing that the weight of the rod is 10 N.

    已知杆是10N.

    determine 求

    (a) the distance h (a) 距离/高度h

    (b) the tension in the cord (b)绳子的拉力/拉力

    (c) the reaction at B. (c)B的反作用力

    有图的话应该更好理解,不做物理题好多年,大致应该是这样的,我不能保证精确~就像后面那个求绳子的张力还是拉力,我也不是很清楚.如果你正在学物理的话,你应该可以根据我给你的大致翻译明白题意~,提问中的两个量“h”和“B”应该是在题目的图片中又所标示吧.
