The truss supports a 100-kN load at J. The Horizontal members are each 1 m in length.
a) Use the method of joints to determine the axial force in member DG
b) Use the method of sections to determine the axial force in member DG
(HINT: you can solve both a and b without solving for the reactions at A and E.
