Example 2 of Method of Sections: Determine the force in member EB of the FBD of the roof truss shown in the Figu below. Indicate the member in compression (C) or in tension (T). 1000 N 3000 N 1000 N 1000 N B -2 m-2m-2m 2m 4000 N 2000 N

For the truss loaded as shown, determine the member forces in BC, CF, and FG in kilonewtons. Use the method of sections. (Due to the nature of this problem, do not use rounded intermediate values in your calculations- 8 kN 3 kN 27 kN 3 kN 4 m H F G 3@3m =9m Fec magnitude kN sense compression FCF magnitude kN sense tension magnitude kN sense tension Also, identify all zero force members in the truss. (Enter your answers as a comma-separated list.)

Calculate all the member forces for the truss shown. Indicate whether tensile or compressive.

Given is a truss structure: Where: Working shear stress for the rivets is 70 MPa Working bearing stress due to rivets is 140 Mpa Thickness of the member is 5 mm Thickness of the Gusset plate is 6 mm Rivet diameter is 15 mm Determine the no. of rivets to fasten the member BD 80 kN 120 kN B. 3 m E 200 kN 4 Panels @ 4 m = 16 m

I need the answer as soon as possible

Plz

Consider the 21-member truss shown; determine the zero-force members and force in each member then state if they are in tension or compression.(Support on point B and C are pinned and roller, respectively)

Determine the smallest safe cross-sectional areas of members CD, CI and CHfor the truss shown. The allowablestress are 100 MPa in tension and 80 MPa in compression. Indicate tension or compression.(Draw the required FBD and answer in ??2).

Answer upto three decimal places

From the Given Truss Shown: P= 31 KN M=128 KN Calculate the Force Carried by member Gl. If the member is compression put negative (-) sign. PKNJ h=8m B A PKN D PKN MkN MKN MKN PKN I H -6 panels @ 5 m 30 m PKN
