The Howe bridge truss shown is subjected to the given loading. It is discovered that the material out of which some of the

members of the truss are made might not be strong enough to support the forces acting on them. The main members in

question are members $HD,CD,$ and $GD$ of the truss. It is desired to determine the force in each of these three members,

$HD,CD,$ and $GD,$ so the strength requirements of these three members can be known and compared to the strength

capacity of the material out of which these members were constructed.

using the method of sections.

Rank the options below.

Perform equilibrium analysis on the entire truss to determine the reactions at the truss supports at A and E $.$

If necessary, divide the truss, again, and perform equilibrium analysis on one of the divided sections in order to determine the forces in the remaining desired members.

Perform equilibrium analysis on the specified section of the truss to obtain the forces in the desired members that were cut in half.

Draw a line through the truss to separate it into two sections, making sure the line passes through one of the members whose force is to be determined but no more than three members total.
