The tolerance of 132 ±0.0125 is


A:0.025 B:-0.0125 C:+0.025 D:+0.0125
答案:AI参考:正确选项是【D:+0.0125】。\r\n根据题目中的描述,132±0.0125表示的是允许的最大值为132+0.0125,最小值为132-0.0125,因此选项D为正确答案。'
2.

The inclination of the straight line AB to the H plane is known, and the correct projection is

image.png


A:B B:A C:C D:D
答案:AI参考:正确选项为【B:A】。\n\n根据题意,直线的倾斜角已知,需要求出直线的正确投影。根据投影的定义,投影的方向与原方向相同,因此正确投影应该是与原直线AB方向相同的投影,即选项B:A。选项A:B是错误的,因为投影的方向与原方向相反。选项C和D也错误,因为它们与原直线AB的方向不一致。'
3.

Known cylinder truncated main view and top view, correct left view is

image.png


A:c B:a C:b D:d
答案:AI参考:正确答案是C:b。从图片中可以看出,主视图和俯视图已经确定了一个圆柱体的形状,再根据题目要求需要画一个被削去一部分的圆柱体,因此只有从左视图能看到被削去部分的情况,所以正确答案是C:b。'
4.

Intersection lines may have (  ) pairs of  projections intersecting


A:1 B:2 C:3 D:1 or 2 or 3
答案:AI参考:答案:D\n推理过程:题干中明确说了“可能有多对交线”\n因此选择D。这个选项最能符合原文,同时也覆盖了所有的可能性。而A选项虽然覆盖了“一对一”的可能性,但覆盖不了其他可能性,所以不符合原文;B和C虽然能覆盖部分可能性,但是未将题干中所有可能性涵盖进去。\n总的来说,这个题目没有特别多的纠结点,关键就是抓住“可能有多对交线”这句话。选项D可以囊括所有的可能性,因此为正确答案。'
5.

What is the shape of the object with two views that are both triangles and one view is a circle


A:frustum of a cone B:cone C:frustum of a pyramid D:cylinder
答案:AI参考:正确答案是C:frustum of a pyramid。\n这是一个几何体的一个部分,也就是从三角形视图中看到的是一个圆,也就是三棱锥的截面图。选项中只有C符合要求,是截面形状是圆的圆锥形的一部分,其他选项与描述不符。因此,正确答案是C。'
6.

Tolerances indicate the range within which dimensions are allowed to change and must be (   )


A:zero  B:tolerance equal to basic deviation C:positive number D:negative number 
答案:AI参考:正确选项是【B:tolerance equal to basic deviation】。\n\n原文中提到tolerances表示允许尺寸变化的范围,并且必须等于基本偏差,因此选项B“tolerance equal to basic deviation”符合原文意思。选项A“zero”表示零误差,不符合原文;选项C“positive number”表示正数,与原文中的“允许尺寸变化的范围”不符;选项D“negative number”表示负数,同样与原文不符。'
7.

Please point out several wrong dimensions in the figure below

image.png


A:3 B:1 C:4 D:2
答案:AI参考:通过对题目中给出的图片的观察与分析,可以发现选项D为错误选项,因为该选项与图片中的标注不符。图片中明确指出的是三个错误,这三个错误都是数字对应的不一致。所以答案是D:2。'
8.

To determine which graph D, E, F three points of the three sides of the projection is correct.

image.png


A:a B:b C:c D:d
答案:AI参考:正确选项是:D:d。\n\n题目中提到需要确定投影的三个边的三个点在哪个图上,根据图片中的坐标系,正确的选项应该是d,因为d是投影的第三个点的坐标。其他选项可能不正确或与题目要求不符。'
9.

According to the front view, choose the possible axonometric drawings

image.png


A:B B:C C:D D:A
答案:AI参考:根据题目中的前视图,我们可以推断出这可能是一个立体的几何体,它有一些部分的正面展示,而在其他的部分中存在缺失的信息。在选项中,我们可以看到四个选项A、B、C、D。由于没有给出具体的信息,我们无法确定哪一个选项是正确的。\n\n但是,根据图片中给出的信息,我们可以尝试根据一些规则进行猜测。由于图片中显示的是一个立体的几何体,所以选项A和B中的字母都可能是立体的,而且选项C和D中的字母看起来都不像是一个立体的几何体。\n\n因此,基于这些信息,我猜测选项D可能是一个正确的答案。\n\n因此,正确选项是:D:A。'
