不同点：公理一中的两个力分别作用在两个不同的物体上；公理二中的两个力作用在同一物体上。

2.答:通过B点,由B点指向C点。

因为在主动力F1的作用下, C点的运动趋势方向向上,根据三力平衡汇交定理可知F3的方向是由B点指向C点。

3.答:刚体不会平衡。

因为刚体受两力偶( F1, F1 ')和( F2, F2 ')作用产生顺时针方向转动。

4.答:不对。

力偶矩是由力F '对O点产生的矩平衡的。

5.答:力偶的等效性有: (1)只要保持力偶矩大小和转向不变,力偶可在其作用面内任意移动,而不改变其作用效应。

(2)只要保持力偶矩大小和转向不变,可以同时改变力偶中力的大小和力偶臂的长短,其作用效果不变。

图中d1< d2,若F1×d2= F2×d1,只要F2> F1,丝锥的转动效应会保持不变。

装配时，不需辅助加工和修配，大大提高生产效率。

加工零件时，可以采用高效率的专用设备，成本显著降低。

从设计方面看，可以简化绘图、计算等工作。

螺栓、螺母等具有互换性，汽车零部件也具有互换性。

2．答：公称尺寸是设计者根据零件的使用要求，通过计算、试验或按类比法确定的尺寸。

3．答：极限尺寸是尺寸要素允许的尺寸的两个极端，分为上极限尺寸和下极限尺寸。

上极限尺寸是指尺寸要素允许的最大尺寸，下极限尺寸是指尺寸要素允许的最小尺寸。

4．答：上极限偏差是上极限尺寸减其公称尺寸所得的代数差，下极限偏差是下极限尺寸减其公称尺寸所得的代数差。

5．答：尺寸公差是允许尺寸的变动量，等于上极限尺寸减其下极限尺寸之差，或上极限偏差减下极限偏差之差。

五、计算题1．解：尺寸公差T h=︱ES－EI︱=︱（+0.034）－（-0.040）︱=0.074㎜上极限尺寸D up=D＋ES =72＋（＋0.034）=72.034㎜下极限尺寸D low =D＋EI=72＋（-0.040）=71.960㎜2．解：尺寸公差T s=︱es－ei︱=︱0-（-0.033）︱=0.033上极限尺寸d up =d＋es=30+0=30㎜下极限尺寸d low =d＋ei=30＋（－0.033）=29.967㎜3．解：上极限偏差es=d up－d=40.024-40=＋0.024㎜下极限偏差ei=d low－d=39.985-40=-0.015㎜尺寸公差T s=︱es－ei︱=︱（＋0.024）－（-0.015）︱=0.039㎜图1—14．解：a）b）c）图1—25．解：（表中红色文字为答案）㎜六、综合题1．（1）答：㎜（2）答：㎜2．答：（1）内测量爪测量孔及槽宽的尺寸（2）紧固螺钉将游标固定在尺身上（3）主尺用来读取尺寸的整数部分（4）深度尺可测孔及槽的深度（5）凸钮用于推拉游标（6）游标用来读取尺寸的小数部分（7）外测量爪测量零件轴及厚度的尺寸（8）0.02㎜3．答：（1）0.0213.08（2）0.0210.88（3）0.0529.55（4）0.058.90七、检测题（略）课题二公差代号与尺寸检测一、填空题1．20IT01IT182．零线3．大小小写4．上0下05．f（精密级）m（中等级）e（粗糙级）v（最粗级）6．常用轴常用孔优先7．基本偏差代号公差等级1．× 2．× 3．√4．× 5．√6．√7．× 8．√9．√10．√11．× 12．×三、选择题1．C2．A3．A4．C5．B6．C7．C四、问答题1．答：基本偏差是指，在公差带图中，靠近零线的那个极限偏差。

《机械基础（少学时）（第二版）习题册》参考答案绪论一、选择题1．A2．A3．ACB4．BAC5．A6．A7．C8．C二、判断题1．√2．×3．√4．×5．√6．×7．√8．×9．√三、填空题1．机器机构2．动力部分执行部分传动部分控制部分3．制造单元4．进给手柄钻头5．滚动轮接触凸轮接触齿轮接触6．滑动大低不能四、名词解释1．机器是一种用来变换或传递运动、能量、物料与信息的实物组合，各运动实体之间具有确定的相对运动，可以代替或减轻人们的劳动，完成有用的机械功或将其他形式的能量转换为机械能。

2．机构是具有确定相对运动的实物组合，是机器的重要组成部分。

3．构件组成机器时，必须将各构件以可以运动的方式连接起来，两构件接触而形成的可动连接称为运动副。

4．两构件只能沿轴线做相对螺旋运动的运动副叫螺旋副。

五、问答题1．两构件之间为面接触的运动副称为低副。

低副按两构件之间的相对运动特征可分为转动副、移动副和螺旋副。

2．低副的特点是：承受载荷时的单位面积压力较小，故较耐用，传力性能好。

但低副是滑动摩擦，摩擦损失大，因而效率低。

此外，低副不能传递较复杂的运动。

3．两构件之间为点或线接触的运动副称为高副。

按接触形式不同，高副通常分为滚动轮接触、凸轮接触和齿轮接触。

4．高副的特点是：承受载荷时的单位面积压力较大，两构件接触处容易磨损，制造和维修困难，但高副能传递较复杂的运动。

5．常见的机器有变换能量的机器、变换物料的机器和变换信息的机器等。

6．零件是机器及各种设备中最小的制造单元。

机器由若干个运动单元组成，这些运动单元称为构件。

构件可以是一个零件，也可以是几个零件的刚性组合。

7．在机械装配过程中，往往将零件先装配成部件，然后再装配成机器。

2.答：为真正实现安全的电子商务必须要求电子商务能做到机密性、完整性、认证性、有效性和不可否认性，只有满足了这些条件的电子商务才能称的上是安全的电子商务。

3.答：这个安全体系至少应包括三类措施，并且三者缺一不可。

一是技术方面的措施，技术又可以分为网络安全技术,如防火墙技术、网络防黑、防毒、虚拟专用网等，以及交易安全技术,如信息加密、安全认证和安全应用协议等。

但只有技术措施并不能保证百分之百的安全。

二是管理方面的措施，包括交易的安全制度、交易安全的实时监控、提供实时改变安全策略的能力、对现有的安全系统漏洞的检查以及安全教育等。

三是社会的法律政策与法律保障。

电子商务安全性首先依托于法律、法规和相关的管理制度这个大环境，在这个大环境中，运用安全交易技术和网络安全技术建立起完善的安全管理体制，对电子商务实行实时监控，并加强安全教育等，从而保证电子商务的安全性。
