Equilibrium –Problem
Determine the reactions at A and the force in bar CD due to the loading.
Equilibrium in 3-Dimensions
In two dimensions, the equations are solved using the summation of forces in the x, y and z directions and the moment equilibrium includes moment components in the x, y and z directions.
Trusses -Definition
Trusses are structures composed entirely of three force members in the form of trianghle . They consists generally of triangular sub-element and are constructed and supported so as to prevent any motion.
Simple Truss
It has been observed that the analysis of truss can be done by counting the number member and joints on the truss to determine the truss is determinate, unstable or indeterminate.
Method of Joints -Truss
means of solving force inside of the truss use equilibrium equations at a joint. This method is known as the method of joints.
