Determine the force on each member of the truss and state
if the members are in tension or compression. Set
P1 : 500 lb and P2 : 100 lb.
Method of Joints: In this case. the support reactions are not required for
determining the member forces.
Determine the force in members HG. HE. and DE of the
truss. and state if the [nembels are in tension or compression.
Method of Sections: The forces in members HG. HE. and DE are exposed by
cutting the truss into two portions through section
