4.3 ANALYSIS OF TRUSS
Two common method used:

i. Method of joint
ii. Method of section

Method of Joints is used by drawing free-body diagrams for every member of the
truss and solving the equations for equilibrium.

Method of Sections is a method used to determine the forces in certain members, rather thanthe

whole truss.

Example 1

Apply the method of of joint to determine the force in each of the truss shown in figure 1.State

whether each member is in tension or compression.
