Problem 4. (25%) The truss shown in the figure is supported by a pin at H and a roller at A. Use method of sections to determ

Answer 1

Answer #1

Solving the truss by ''Method of Section".

In this taking a section XX passing through DF,EF and FG and considering all forces to the right side of the section.

Before this evaluate the reaction.

Let, Ay be the vertical support reaction at roller support A.

Let, Hy and Hx be the vertical and horizontal reaction at pin support H.

Hx 2000 EF=이 1 the t-ne Ay + Hy - soo - 200 - 500 - 400 Ay + Hy = 1200 0 EMH=0 б+ - yoox 8 + 500x16 + 200 X24 + goox32 - Ayx3
