SUMMARY

The discussion centers on the approach to solving a wrench reduction problem in mechanics. The user outlines their method of calculating resultant forces and moments, specifically using the force vector F_r = 500i + 300j + 800k and the moments about point A, M_x_A = 3200 and M_z_A = 1800. The user expresses uncertainty about the next steps in their calculations and seeks clarification on potential conceptual misunderstandings. The conversation highlights the importance of correctly decomposing moments and understanding the application of forces in three-dimensional space.

This one is really discouraging me. It looks sooooo easy since the forces are each in one direction

The way I have usually handled these as a procedure is: Find [itex]F_r[/itex] and then find [itex]M_r[/itex] about some point and then decompose [itex]M_r[/itex] into components that run parellel and perpendicular to [itex]F_r[/itex]. Then I can usually find P(x,y)

If I were to move everything to point A I would have:
[itex]F_r=500i+300j+800k[/itex]
And I would also have to find the couple Moments about A:
[itex]M_x_A=4(800)=3200[/itex]
[itex]M_y_A=0[/itex]
[itex]M_z_A=6(300)=1800[/itex]

I am just unsure where to go from here? Or is this all wrong altogether?

I have done this one over soooo many times. I am clearly missing a crucial conceptual point. ANY hints or criticism would help.
 
Well Good Morning!
