The following procedure provides a typical means for analyzing a truss using the method of joints.
Draw the free-body diagram of a joint having at least one known force and at most two unknown forces. (If this joint is at one of the supports, it generally will be necessary to know the external reactions at the truss support.)Use one of the two methods described above for establishing the sense of an unknown force. Orient the x and y axes such that the forces on the free-body diagram can be easily resolved into their x and y components and then apply the two force equilibrium equations∑Fx=0 and ∑Fy=0.Solve for the two unknown member forces and verify their correct sense.

Answer 1

下列程序提供了一个典型的手段来分析一架用这个方法。

图绘制free-body共同拥有至少一种已知的力量和最多的两个不知名的力量。(如果是在一个共同的支持,这通常会有必要了解外部反应在桁架的支持。)使用上述两种方法的建立一个未知力的感觉。定位x轴和y轴上,free-body图可以很容易地解决进入他们的x和y组件,然后涂上两力平衡方程∑Fx = 0 = 0 .∑专项解决的两个不知名的成员的力量和验证他们的正确的意义。
