lA411011  桿件的基本受力形式

   結構桿件的基本受力形式按其變形特點可歸納為以下五種：拉伸、壓縮、彎曲、剪切和扭轉。
1A411012  桿件強度的基本概念
   結構桿件在規定的荷載作用下，保證不因材料強度發生破壞的要求，稱為強度要求。
lA411013  桿件剛度的基本概念
   結構桿件在規定的荷載作用下，雖有足夠的強度，但其變形也不能過大，超過了允許的范圍，也會影響正常的使用。限制過大變形的要求即為剛度要求。
   梁的變形主要是彎矩所引起的，叫彎曲變形。剪力所引起的變形很小，可以忽略不計。
   影響位移因素為：
   (1)材料性能：與材料的彈性模量E成反比。
   (2)構件的截面：截面越大慣性矩越大，與

lA411011 rods form the basic force

   The basic structure of rods form their force deformation characteristics can be summarized in the following five categories: tension, compression, bending, shear and torsion.
1A411012 bar the basic concept of strength
   Structural Rod in the prescribed loads to ensure that no damage occurs due to material strength requirements, known as the strength requirements.
lA411013 the basic concepts of Stiffness
   Structural bars under the prescribed load, although adequate strength, but the distortion can not be too large, exceed the permitted range, will also affect the normal use. Too restrictive requirements shall deformation stiffness requirements.
   Beam deformation is mainly caused by the moment, called the bending deformation. Shear deformation caused by small, can be neglected.
   Factors affecting the displacement:
   (1) material properties: elastic modulus and inversely proportional to E.
   (2) members of the section: the larger section of the greater moment of inertia, and
