Any force is correspondingly designated by the letters of the two spaces separated by its line of action. Force polygon is drawn first at some suitable scale.

The points will be located by drawing the lines in true sense surrounding these points. For example, af and ef are drawn and where they will intersect, they will give the point f. Magnitude of the force Sense of the force tension or compression Length of the line af will show the magnitude of the force in member af.

Direction of af is downward and towards the joint A means the force will be directed towards the joint. Force directing towards the joint is compressive and af will be in compression. Now it reads fa. Syed Ali Hasnain Naqvi. Andrei Lucian. Bevianto Demas Putranda. Indian Abacus. Tfk Baja. Joseph Cloyd L. Florin Panianopol.

Maxwells DiagramMaxwell diagram is the second step while calculating the forces in truss members by Graphical Method, after Bows notation. After completing the force polygon of applied forces and reactions, we will locate the intermediate points f, g, h, i, j.

Interpreting Maxwell DiagramWe can find the following attributes of the truss member from the Maxwell diagram. Magnitude of the forceSense of the force tension or compression. Direction of af is downward and towards the joint A means the force will be directed towards the joint. Now it reads fa.

Now fa is directing upward i. ExampleFor the same truss use the Graphical Methodto construct a Maxwell diagram and find the forces in the membersFirst find the reactions. First annotate using Bows Notation label spaces between members and forces First find the reactions. This locates jProceed to k in same way and half the truss is solvedMeasure all lines - this gives the force in each memberneed to use a special convention to determine tension or compression.

The points will be located by drawing the lines in true sense surrounding these points. For example, af and ef are drawn and where they will intersect, they will give the point f. Magnitude of the forceSense of the force tension or compression Length of the line af will show the magnitude of the force in member af.

To find the sense, draw FBD of joint A and read clock wise. Force directing towards the joint is compressive and af will be in compression.
