What are the integral method and isolation method in physical force analysis

How to understand the whole method for force analysis
Physics

The integral method is a means of physical force analysis, and the isolation method is usually used together. The integral method is used first and then the isolation method. Of course, there are conditions, that is, the acceleration of the whole system is the same,
First the whole: the external force on the system = the total mass of the object in the system * acceleration a, which is to calculate the acceleration
2 post isolation: for the analysis of single object in the system, generally find the one with less force, make the force analysis diagram, and then according to the unknown quantity required by the force balance hill
(there are no questions. Some of them are very difficult. There are special aspects in stress analysis. Specific problems should be analyzed in detail.)

How to use the isolation method of stress analysis

1、 Isolation method: in order to find out the force and motion of an object in the system (connector), In general, isolation method can be used. The basic steps of using isolation method to solve problems are: (1) defining the research object or process and state; (2) isolating a research object or a certain movement process or a certain state from the whole process; (3) drawing the force diagram or movement process diagram under a certain state; (4) selecting appropriate physical laws to solve equations The basic steps of using the holistic method to solve problems are: (1) to make clear the whole process of the system or motion; (2) to draw the diagram of the whole process of the force or motion of the system; (3) to choose the appropriate physical laws to solve the equations
