he force-couple system shown can be replaced by a single equivalent couple C^R.Determine C^R

SOLVE STEP BY STEP IN DIGITAL FORMAT Determine by the method of nodes, the forces at which all the members of the following trusses work. Place the results of each force in the members of the truss drawing for qualification. 1200 N 300 N A B oolco 0.00 3 m E 4 m 4 m

Need neat and clean handwritten solution of both the parts with proper explanation..if you are not capable of doing than do not attempt  as you will get downvote...

Please explain how they got these values along with the steps used to find them.

The beam cross section shown below has been proposed for a short pedestrian bridge. The cross section will consist of two pipes that are welded to a rectangular web plate. Dimensions of the cross section are: h = 470 mm tw = 14 mm d = 120 mm t = 9.6 mm Additionally: • The area of each pipe is A = 3330 mm2. • The moment of inertia of the entire beam cross section about the z centroidal axis is IZ = 428040000 mm4. If the beam will be subjected to a shear force of V = 225 kN, determine the shear stress at point H, located at yH = 110 mm above the z centroidal axis.

Determine the force in members BC, GA, and BG of the truss shown in the figure below. Let P = 175 kN. NOTE: If your answer is a compressive force then just put a negative sign. If your answer is a tensile force then just type the answer directly. (ALSO, DON'T FORGET THE UNITS) 2P 2P 30 60V60° 60°V60° C 30 D 3P 4m 4m 4m Solve the force in member BC. Solve the force in member GA. Solve the force in member BG.

Please answer this question by showing every step of the process and do highligh the answer at the end for me please. Please solve it in a way so that I can understand every step you did.  Thanks in advnace.!

If you wanted to find the y-centroid of the shape below using the volume element shown, you would need to express the length Lin terms of y. O True O False
